BuddyPress.org

Okay, I installed it on the main site page (as a WP plug-in, not MU plug-in). With plug-in installed, the top bar (My Account, My Blogs, etc.) does not appear. Interaction with Facebook works somewhat, for example it is possible to invite Facebook friends to the blog. However, the login doesn’t seem to work well, and there is no logout option.

This has potential but must work nicely. Can someone advise how to get it working in WPMU?

Thanks.
