I have a main site that is a buddypress site. I later converted main site to a multisite configuration. Now, when people sign up they are put on my network administration dashboard as a user and not my main site as users and they don't have roles. What did I do wrong?
Did you install related plugins for users ? Because there are certain plugins that when people register then they come across all websites (e.g http://wordpress.org/extend/plugins/multisite-user-management/)
