BuddyPress.org

Sidenote: The whole WPMU process of adding an existing user to an existing blog is painful. You need to know the username and the email address of the user you want to add! I guess this is done for security reasons… but if you’re a site-admin, knowing the username should be enough (I guess you could use the “Site Admin > Blogs” option as well, but anyway…).

I’m going to test out Burt’s BP Community Blogs plugin to see if it makes things easier.
