BuddyPress.org

If you’re looking for a plugin which allows members to customize their profile pages in much the same way as Ning (but without the drag and drop of page elements) there is a premium Advanced Profiles plugin available from http://www.social-network-solutions.com/BuddyPress

It’s built by the same team who’ve developed Member Map and Listings apps from Ning (which I use on that platform), and I’m now using it on two BP networks. Members seem to use it intuitively, and the customer support is great. I know a lot of us either can’t afford/feel uncomfortable about paying for plugins, but it certainly works well.
