20 Dec WPMU + Buddypress + BBPress = hat trick of awesome
Whoa, I can't believe I overlooked this news. (Actually, yes I can - Ron was sick, my "baby" turned eight years old, and now I'm sick).
And then BBPress reached a milestone.
WPMU 2.7 still hasn't been released, but the trunk is not as buggy as you might expect.
And, reported by a few people you can run them all *together*.
I think I need to go lie down.
Update: The Revered Jim (who I'm sure never sleeps) has edupunked this all into submission and whipped up a *tutorial* for it.
