BuddyPress.org

For what it’s worth, the site that I’m currently working on (but may not end up) porting to Buddypress is basically a Vanilla forum with a bunch of stuff bolted on, and my 1000-or-so users would kill me if the forum model were not the centerpiece of any new home I put together, although they’re excited about all the shiny new toys that the socialnetworking hoohah can offer.
