For anyone working on buddypress/wordpress communities for the first time, don't listen to what the pages tell you up top. It says "All Wordpress/Buddypress pages need their own page to function right". Well, sometimes activate won't work if it's not aligned with register page. Just a heads up for anyone who tried to join social buddies, and did not get through, please come back over and try again.

Social Buddies! is now open and you should be able to register with no problem.
