I don't know how much support the forum would recieve from members, or how frequent, and I'd be inclined to say no. The IT forum isn't just for problems, "IT" does cover graphics too, and I think keeping the threads mainstream would be more appropriate at this point in time.
I'd be interested to see what sunny and anti think of the idea, but as I stated, I don't believe there would be enough frequent posting there to warrant a new subforum for the content.
