BuddyPress.org

Also check out the well-supported themes by the wpmudev.org group… they cost, but they will provide fantastic support and are guaranteed to work with all upcoming BP updates… Agree with @modemlooper …. the beauty of BuddyPress is you can do anything… the caveat with that is you have to spend a lot of time figuring it all out, trying things, and you might even need to learn a little “programming” along the way to make it do what you want…
