✔ WHAT IS K2?
K2 provides an out-of-the box integrated solution featuring rich content forms for items (think of Joomla! articles with additional fields for article images, videos, image galleries and attachments), nested-level categories, tags, comments, a system to extend the item base form with additional fields (similar to CCK for those acquainted with Drupal), a powerful plugin API to extend item, category and user forms, ACL, frontend editing, sub-templates & a lot more!
Using K2, you can transform your Joomla! website to a news/magazine site with author blogs, product catalogs, work portfolio, knowledge base, download/document manager, directory listing, event listing & more, all this bundled under one package!
Give K2 a try & you'll instantly love it! It's easy to use and fun to develop websites with! If you need any help or want to contribute to the project, join us at the K2 community.
Since K2 is extensible with additional fields to its base item form, you can easily create category-specific content types, e.g. article, blog post, product page, directory listing.
K2 offers as standard:
- nested-level categories (no section/category restrictions)
- commenting, integrated with Google's reCaptcha & Akismet
- item image (useful for articles/catalogs)
- image galleries
- user pages (author blogs/user profiles)
- smart ACL for frontend editing
- unique plugin system to extend item, category & user forms
- ajax-based frontend editing
- ajax-based comments moderation
- Google AJAX Search integration
- Rest-like JSON/JSONP content output
- Native advanced SEF options (added in K2 v2.6.4+)
K2 fully supports the Joomla! API, which means all Joomla! plugins will function properly within the K2 component & modules, either in the frontend or backend.

Do not expect to get any support with this product at all.
Personally i would rather PAY for something and get answers to my questions then be completely ignored on their forums.
K2 is a FREE extension. It's community supported. Saying K2 is "bad" because you don't get any support is like saying e.g. Joomla! is "bad" because no-one replied to some question of yours in the forums.
If you ever wanted premium support, you could have used the forum board dedicated to that. You simply post what you want done by some professional and people get in touch with you.
I would honestly consider what you wrote if you didn't have the option above, but you do. If you're getting paid for the site you deliver, you should also consider paying people to help you out.
At first I was really excited. I installed the extension and went off to find tutorials on how to use it. This is where my problems with K2 begin and end. I found videos and text on WHAT K2 is designed to do, but not on HOW to actually do it.
I've searched and searched for the documentation and steps on how to perform steps, but I can't find them. If they are out there, I sure couldn't find them on the K2 site. I did find a good start on webcafeclub.com but unfortunately the author is still quite a ways from finishing her tutorials, though she has outlined the steps involved beautifully.
In my opinion, K2 is not for beginners. If you are a seasoned developer maybe the lack of good training documentation won't be a problem for you, however if you are a beginner I suggest staying away from K2 until a complete training series is available.
If I do find usable documentation on how to use K2, I will come back and share my findings if they make the extension usable.
Indeed, written documentation is lacking. But there is a wealth of videos in the K2 Community at getk2.org/community that cover almost any aspect of K2 administration.
Furthermore, I challenge you to devote some extra time to get to know K2. It's been built using very few "conventions" (aka stuff you need to figure out). It's mostly built out of plain logic. E.g. why should core Joomla article category options exist in the menus (???) and not the category itself? In K2, category options exist in the category edit page itself. Not somewhere else.
Like I said, devote some extra time and you'll see why so many people have given 5 stars to K2 and most importantly, you'll see why K2 powers today's biggest Joomla! deployments worldwide.
As Joomla! community legend, Amy Stephen, recently said on Twitter: "Thanks for K2. You picked up the ball for Joomla for a long time." https://twitter.com/#!/AmyStephen/statuses/156475956096286720
In short: K2 just works. It should be integrated in the Joomla core as far as I'm concerned. But don't make a mistake about it, K2 is NOT a content construction kit (cck), it's just an extension that extends (or actually replaces) Joomlas content structure.
Of course K2 is not perfect and has his limitations and negative things, for instance it's not possible without core modifications to remove user pages and its html structure could be improved for SEO and other things. It doesn't use h1 tags for article topics and uses h3 tags for article topics in category blog view instead of better suited h2 tags (which are used in article view).
K2 is easy to learn and probably suited for most Joomla beginners, but sometimes you want to go beyond K2's default capabilities, for which you HAVE TO make code modifications. If you aren't a coder, your first place to ask is of course the k2 support forum, but here's the thing, there is a high chance that you won't get support at all there. Most topics are left unanswered, there are only 2 moderators for the beginners section and currently the forum is spamed a lot by I believe bots (could as well be some morons, though).
To make it short:
* If you want a content extension that just works how it should for most cases and can live WITHOUT support (you have to trial and error a lot), then K2 is the right extension for you.
* If you want a content extension but can't afford no support, then something else is better suited for you.
* If you are a pro and want a flexible content extension, don't mind K2 then, use SEBLOD instead. SEBLOD is a real content contruction kit and is by far superior than K2 and any of its competitors, but it's very hard to learn and the documentation is somewhat lacking.
SEBLOD also depends on com_content, the Joomla! core article system. And this creates performance issues the least. K2 on the other hand is completely standalone as a component within Joomla! and has no other dependencies. This allow for more flexibility and better performance compared to any other "content" extension.
On a sidenote, we never say K2 is a "CCK" component. We always say it's a powerful "content" extension with CCK capabilities. Basically what 99,9% of users will ever need ;)
I have used this on many of my clients websites.
The only negative I could put forward is that large amounts of customization will require a Joomla Developer (No problem for me, as I am one!).
Keep up the good work K2 team!
The only problem is the support. You must be prepared to find and solve anything by yourself. The forum is problematic (spam bots are doing a great job over there) and you must be very lucky to get any answer from the community. A payed version with support would be great...until then if you want to use it professionally make sure that you have a decent knowledge of PHP/CSS e.t.c and many weeks of testing the component before going live with things.
What you say is utter nonsense. K2 simply uses Google's reCaptcha service. It's a third-party service, you know, one that is not installed on your server. How has this affected your site's "performance" is another story. Probably a Christmas one...
Nevertheless, I wish K2 team best of luck, inspiration and a lot of improvement over the years to come!
You're "working" with Joomla! since 2005 and you don't see the benefits of K2 compared to the default Joomla! article system? Now that's the joke...
Unbelievable!! It is the most comprehensive bundle out there and you should be clicking the Download button without even thinking too much about it.
You will NOT regret it… I’m lost for words which is hard for me!
You install it to J1.7 and off you go, you make an article form and once you have the basics, you go to tagging which normally you have to remember all the keywords in your website yourself, but no it does it for you. It is a no brainer.
The ratings and review process is also a godsend and thanks to you it is perfect.
One small bug to me though, is the process of not being able to copy and paste from articles in word or wherever to inside the K2 article process which is really annoying, but other than that it is perfection.
Thank You guys.
I've been using K2 in all my customer's sites and portals and have no plans of changing: it just works, like they would expect.
For now, it's an essencial enhancement to the way one can build and display content. And if you want customers to upload content themselves, there is no easier way of doing it: not only frontend editing works like a charm, even in multilingual sites, but also K2 ACL is powerful enough to manage publishing workflow.
And the inbuilt K2 presentation capabilities (the category "blog" layouts) will blow your customers mind, without making waste a ton of development hours to get the right view.
To get the most of it, some of the K2 plugins are truly mandatory, like the extended image and the extended fields. Play around with them and you will find out why.
Of course K2 has it's limitations (field search, image cache, user profile extensibility,...): it's a trade-off between ease of use and flexibility. But for 80% of the sites (not web-aplications), K2 will do the job with an ease of use and presentation flexibility no yet available in Joomla core. And the great news it that even a newbie will be able to get it up and running in no time. A great advantage over other CCK. Not to mention the no-thrills frontend editing that customers love.
The community sometimes takes a while to reply, but they eventually do, and there is lots of information in the forum, one just has to dig-in.
Overall one of the best components available for content publishing.
Thank you Fotis, you are great
First of all, we have a distinct bug tracker for posting any bugs. It's here: http://code.google.com/p/joomlaworks/issues/list
Secondly, I doubt the "several bugs" you mention have anything to do with K2. K2 is a solid content platform for Joomla!. If you are a newbie with Joomla! in general, I'd suggest more trial/error attempts if you don't want to wait for someone to answer to you in the forum.
K2 is quite popular, so some posts may skip answers. But that usually happens to posts that are already answered and the posters are really bored to run a search before posting...
K2 best feature is the templating system. It's easy to understand and very mighty. You can use K2 as a blog, answering system, magazin style portal, for static content, as download system, even as a forum. As a middle class developer, you can understand the code of K2 really fast. It's no magic.
The support is very good. I have wrote Fotis much times over twitter, joomlaworks forum and the google code issue tracker and he responses very fast. And most of the problems was Beta related. The stable versions until K2 2.4.x have almost no bugs. I can't find them...
As you can see the flexiblity of K2, you can use it for 98% of the entire Websites of the world.
Where are the cons? I have'nt found any cons!
K2 is really a rock solid component. And when i have in the future three wishes from a genie. One of my wishes are, that K2 replaces the Joomla Article System!
Give K2 a try - it's a big step forward!
I missed in old versions, however, such as I do in 1.7, small things which for a few people are really important.
1) Tagging is painful; these guys in our websites do work intensely in writing news, so they do in an internal system and then copy and paste contents for different fields in each item. As tagging (or in the old way keywording) has to be congruent to provide a good related-grouping, they select keys in their own system, and then copy all the block with comma values and paste. They hate K2 tagging, one-by-one, being such a slow method. So they go to keywords pasting in the old good joomla basic system. It's faster, it's reliable.
2) As we're running different websites, we've hosted all pictures and media files in a big 'materials site', where they are FTP uploaded: I'll not describe the full internal system, but in joomla we paste the url for pictures and so. In K2 you've to upload each picture, one by one, to same website hosting server (or you could FTP them and then selecting manually one by one). Only in case you have internal pictures within the news (not the main one), they can be pointed to an external url address.
So, if you don't need these kind of small things (which in our case do increase a lot productivity, but probably you'll not work in this way), K2 is really big.
