Re: Can a BuddyPress install be an add on to a blog?
It’s not a stupid question, but it is worded a little strangely.
BuddyPress basically works inside/outside of WPMU, taking what is otherwise just a random assortment of administered blogs, and adds a social networking flair on top of it to allow a layer of interaction between registered users and blog owners.
One install of BuddyPress per one install of WPMU.
Does that make sense?
