Re: Extending a single install of Buddypress across domains
Actually…. yeah, you can do this in MU. Theoretically. Buddypress doesn’t care what the domains are, and it’s not multi-site aware. (the old site term, not the new one)
So I’m pretty sure you can do this with the multisite plugin, bp & mu, without too much tinkering.
