Patrick,
Glad to see the blue bubble under your name. We have more good news for you (and everyone else).. we just uploaded JFBConnect for Joomla 1.6. This release has all the functionality of the Joomla 1.5 release and includes all the social modules (fanbox, like, friends, comments, etc), the integration plugins for JomSocial and Community Builder, and the content plugin for automatic Likes/Comments in articles.
We didn't include the profile plugins for K2, Agora, or Kunena because those extensions have no (Agora), limited (Kunena), or brand-new and we haven't had time to test (K2) support for Joomla 1.6.
As stated before, we're calling this a Release Candidate. We've been working on this release for over a month, and testing it methodically, but there's always the chance of us missing something stupid. Should you run into issues, let us know, and we'll be all over it!
Best of luck to you, and have a great weekend!
Alex
