Re: Buddypress on Multisite
What happens with your blog Themes? Do they do not work, or is the display messed up? BuddyPress and MultiSite should work fine and your WordPress themes on sub blogs should display fine with the addition of the Admin bar at the top.
If you want a theme that matches your main blog you can adept the default theme to become a regular WordPress Theme or look at themes that do this for you
