Because of Zen Cart's peculiar way of doing logins, it's not possible to do the "Master Login". JFusion's Doc files explain why. But at least all my Zen Cart users are imported to Joomla properly. My customers do have to login to Joomla separately, but I think that's OK as long as they don't have to register separately.
Setup is a little fussy with JFusion, but it's worth the learning curve because once it's done, you can really walk away and forget about it. JFusion is very reliable and works flawlessly.
I used an earlier version of JFusion about a year ago: I used the VBulletin bridge. Since then, I see that they have improved installation and setup so it's much easier now. And you can install upgrades right over the existing JFusion, without having to uninstall first. I like that!!
JFusion won't be a solution for everyone. If you want to have Zen Cart as your Master program, then it's a great solution.
If you choose Joomla to be the Master program, then there are problems because Zen Cart does not have Usernames. And almost all Joomla programs need them. So if you want to setup a full social site or a bulletin board to work with Joomla, you may run into complications because none of the users will have a USERNAME. And you don't want the email Address to be broadcast to all visitors as the user ID.
JFusion allowed me to set the Joomla login for EMAIL instead of USERNAME. So it works with ZenCart without a hitch.
I am only using Joomla to add a blog, private messages, a game, Twitter link and Ecards. These are things that Zen Cart does not have and I wanted them.
If you wish to have a fully integrated Zen Cart and Joomla social site, you would probably do better with one of the fully integrated packages for Zen Cart/Joomla, which are mentioned in one of the Joomla Forum Threads.
Thank you to JFusion for such an amazing bridge program. It's one of the most awesome products in this Joomla extensions directory.
Of course I chose Chinese as my first sample language, and then discovered that I couldn't read any of the languages in the language list either, so couldn't revert back to English. (I had turned off all the flags: I didn't see the point in using them.) Now I'm using the flags, too, so I can get back to English again. :)
This is a really great module.
There's a trial of the commercial edition where you can try the other features :)
The only tip for new users: make sure your categories have cards in them. If you have any empty categories, the program might not show on the front end. Other than that little discovery, I had no difficulty installing and using RWCards. It's very nice, looks great, and very easy to use.
I make the ECards from photos that my users contribute, so it's also a community project. If you're using Jomsocial, there's a "userpoints" hack for RWCards in the Jomsocial support forums that gives userpoints when the RECEIVER of the Ecard goes to read it on your site.
RWCards can also work like an Invitation system. I created one category with invitations to my site, which any of my users can send to their friends. And, get userpoints!
I'm very pleased with RWCards. It turned out to be much more flexible and useful than I expected. Very, very nice!!
Once that was sorted out, this is VERY easy to setup. I created five articles in one category (one article for each tab.) Then select that category in the 2JTabs module. Refine the settings, put the 2JTabs module in a Position and enable it. It was such a surprise to see it worked immediately without any fussing with the settings. Wow!!
This program is compiled so it's not as easy to do custom CSS but there are 21 style sheets for the tabs so it doesn't matter. Besides, most of the "styling" is done in my articles where there is plenty of freedom for designing.
This module is well worth the modest price. It's just so good!! It adds lots of glamour to the front page of my site, without causing any trouble for anything else on the site.
There are lots of potential uses for this program. I'm so happy with my first set of tabs, I'm trying to figure out how else I can use it, because this was FUN.
