JFBConnect features all the Facebook integrations and the best bit is Sourcecoast.com's documentation on each an every feature. They even cover off in detail on how to configure the Facebook side well when the extension does not do it for you anyway!
I have used it with other social extensions like JomSocial and CommunityBuilder usually just to make use of the profiles and easy registrations with no problems at all.
Would love to see a Kunena integration in the future then it would be the complete package for me. I know its a Facebook integration but perhaps the ability not to publish to Facebook everytime and just your own activity feed?
I am a intermediate Joomla! and web user and this is the only extension I have ever used with out some sort of issue so had to add a review. Good work, keep it coming.
