Gotta say, I’m completely amazed at the brilliant WPMU DEV turnaround speed and comprehensive goodness of this!
(nothing to do with me either, I’ve been out stuck at airports most of the weekend)
But check out the unreal new Ning to BuddyPress plugin now on offer at WPMU DEV.
Of course, this follows the news that Ning has culled free networks, if you really are interested in forming, sustaining and developing a great network (that you actually own!)… BuddyPress is a great place to start :)
