Ercih, if you set your bp groups to be PRIVATE, the forum in that group is actually using bbpress; and will be visible to users that go directly to bbpress itself — they can read, post new topics, edit, delete their topics — just like a normal bbpress stuffs that really defeats the purpose of having a privacy option for BP Groups, i.e. those that is setup with forum.

I hope I am completely wrong; but this is what I am seeing with my wpmu2.8.6+bp1.1.3+bbpress1.0.2
