Or.. is this hallowed MF ground?
I think you're looking for a forum called "Business Discussion" (doesnt exist) because there is a large portion of "pro" photographers that aren't creating high quality images. This might be the reason why it is in the MF forum. It's specifically geared toward MF photographers. I think if you start getting posts on senior portrait business you're going to alienate the commercial photographers. I think its more to keep out certain types of photographers rather than the type of camera. I could be way off though...
