The Joomla! Extensions Directory ™

When you first open up zh Googlemap you think "Whoa, I'll never figure this out". Its so feature rich - there's so much this component can do. But don't be daunted - Go for it.

I've used it for really simple maps and for very complex interactive maps - I mapped a whole state of Australia, breaking it up into approximately 90 individual highly detailed territories (polygons). This component made what seemed like the impossible, very easy. And I've seen what others have done and some of them are amazingly awesome - the detail and the features are mind-blowing.

Once you finish, you think "I wonder if I could add [something/anything]?" YEP! Its all there - anything I can think of, this component does it.

The instructions are a bit difficult - the English is a bit broken, BUT ask the developer on his forum and he's straight back to you with the answer. Can't ask for more.

AND, this component is regularly updated with new features.

I love it. Just excellent.

The thing with these form extensions (and I've tried a few) is the ease of use. I only want something simple and Blue Flame nails it.
I tried a few free ones and was disappointed: They either didn't do the job or they mysteriously malfunctioned or they required a post-grad in IT to make them work at all.
This one is as powerful as you want it to be - has heaps of scope. Its the basics that make it so usable: The interface is so simple and logical to configure and you just build on top of that - solid logical basics.
I don't really give a rat's backside about a few milliseconds here and there, and although others have mentioned it, I haven't found any noticeable lag (I sometimes think people who notice this stuff go looking for it and are akin to those record-freaks who insist digital recordings don't have the same quality as pressed-vinyl and they can hear the difference - yeah right - whatever.
This extension is not free but its close enough and for the price it is a great investment in saved time and frustration.
Buy it - its cheap - it works - it can be as complicated as you want it to be or as easy.

This visitor counter is excellent. Installed first go, effortless to configure, lots of features. I started with the v4 beta and used Joom's Extension Manager Update to load the v5 beta - not a hitch (bodes).
This V-counter is Split into two parts: a module and a component.
--- The module ---
All the features of the best counters (I've used a few) and its straight-forward to configure. It is the module that controls how the counter works (time offsets, IP blocks, bot blocks, etc.) - configuring the counter entire is done inside the module.
One note: It will only count visits to the pages the module is published on - but with so many styles its pretty easy to find the right look for all funnel pages so visitors get counted. I use a horizontal text line style on the footer on every page.
--- The component ---
A back end interface with a full list of all visits with timestamp and IP details. It also has an interface to enter known IPs so regular visitors can be instantly identified.
Note: I can't seem to find a sort or search feature for the component but I have alerted the developer to this. Being a beta release I expect that will be fixed soon.
All up an excellent, easy to use free extension. The developer looks new to extension development but has produced here a really solid offering - his feedback / support seems good too (he's not all jaded like some developers get over time).
Highly recommended.

I can usually figure out anything. I've never given a bad rating but this extension just leaves me wondering "what?". One minute it works fine then it doesn't. Nothing changed so why? I've been over and over it - scanned all the forums - taken all the advice. I give up. Frustrated.

It did what it said: downloaded -> extension manager -> upload & install -> module manager -> simple setting params -> and... it worked first time! Brilliant! Simple -> Love it!

This little plugin is amazing. In every edit window for modules and articles there is the Modules Anywhere “add module” button – press the button, select the module, in it goes and off it goes – it works. This is so easy – the best thing I’ve found in ages for Joomla. I will install it in every Joomla website I make. It should be standard issue.
