Custom Object

As noted earlier in this thread, JFBConnect supports:
* Joomla Content - Vote
* EasyBlog - Rate & Comment
* EasySocial - Upload Image
* JomSocial - A few supported here
* JReviews - Review and List
* K2 - Vote & Comment

Those are the actions that JFBConnect has built in support for in existing extensions. You can also create your own custom buttons for any action that Facebook supports.

I hope that helps explain,
Alex
