Yes, JFBConnect works with CB 1.9.1 and can automatically import their profile information and avatar from any of the 10 social networks we support, including Facebook. You can also import their profile into Kunena, which it sounds like you use as well.
in addition to what it would be nice if you posted on their wall every time : you record , on public zoo or Kunena ...
I'm not exactly sure what you mean here. We do have Open Graph Action support, which is a way to post activity your users take back to their Facebook Timeline. Unfortunately, we don't currently support Zoo or Kunena for these features.
I hope that helps, but if you need anything else, just let me know.
Thanks,
Alex
