Andy,
Glad you fixed the avatar thing. If the solution was anything you think we should know about, please let us know.
As for importing friends, no, that's not something possible out of the box with JFBConnect. With some PHP code you can get a list of a user's friends, but then the question is what to do with that list? We integrate with a lot of different extensions. It may be possible to create auto-connections in each of them, but that also may really annoy some users. If you have any suggestions on what best to do with a list of a user's friends from Facebook, we'd love to hear it. We have thought of a simple "Your friends x,y,z" use this site (by checking if they have Joomla accounts). That still would take some work, and could be problematic for users with huge amounts of friends.
Let us know what you were looking for though, and we'll let you know our thoughts!
Thanks,
Alex
