I Need JFBConnect to work with my Shopping Cart Ecwid Is this Possible

I've never used Ecwid, but if it uses standard Joomla, you should be able to add JFBConnect easily to it. We have a lot of 'easy tags', like {JFBCLike} that you can put on your page for a Like button, as well as the easy registration capabilities among other things. If Ecwid uses standard Joomla (or JomSocial/Community Builder) users, JFBConnect should work just fine.

Unfortunately, I can't give any guarantees about compatibility, but we do have a 30-day money back guarantee if you can't get things going.

Hope that helps,
Alex

SoBe,
If Ecwid doesn't use the Joomla user's that are created, I don't think JFBConnect (or JS or CB) would help you much for user authentication and quick account creation. It would still (likely) help with easily adding Like, Comment, and other social features from Facebook to your pages, but again, that depends on how integrated Ecwid actually is with Joomla.

Without knowing anything about Ecwid, which I don't, it's tough to tell you how our SSO solution would work with theirs. Unfortunately, we can't test with every possible combination of extensions or things that integrate with Joomla, especially with every configuration option. That's specifically why we have our 30-day money back guarantee though, so that if it doesn't all work how you want, at least you aren't at a loss for subscribing to JFBConnect.

Hope this helps explain,
Alex
