IIRC, the whole BF invitation thing is old news? And so what. There are lots of forums to choose from, and many ways to do it.

I belong to a women's only ski board that requires 25 posts for full access, and if you are not female, you WILL be banned. It is not a sub forum of a different board.

I belong to a design entrepeneur board that require that you either purchase a specific book or pay a certain fee.

It's all different, and it's all good and we can all make choices. Personally I think it's bad form to
put down board on another, but that's just me.
