BuddyPress.org

How about bbpress plugins? Do they work, too?

Some will work by putting the bbPress plugin in the /mu-plugins/ folder.

BuddyPress’ embedded version of bbPress does not have a bbPress backend, so try using bbPress plugins that do not have an admin options page.

(I’d try _ck_’s plugins since most of her plugins do not have an admin options page)

Other trickier ones will need to be ported over.
