A photography forum is a great idea - having a single place to discuss the subject rather then posts getting buried amongst other subjects is a positive move, especially when photography is THE link between our solitary hobby and the intenet and everyone else
Over on the CoolMini site we got a photgraphy forum set up, and whilst not being the busiest forum, has resulted in some interesting discussions.
I started a thread there that's now stickied about the camera that people use. It's now 5 pages long and you can check peoples galleries against the camera they use - and it shows good results can be achieved with very modest equipment.
