As much as that is pretty blatant racism, it is on another forum. I don't think it is good to have cross-forum criticism, because that invites forum wars, and MyBB is bigger and more right-wing.
There have been forays of the MyBB right wing here (see above, posts 361-365) thankfully they did not feel welcome.
You just need to have been there for a while and made a few posts. I think you got as far as Honorary Member. I am an Executive Member, but I have no idea of the criteria - you were there for longer than I have and you have a shit-ton more posts.
