I'm evaluating a prototyping software. (Won't mention which one) Their company help section is horrible and it seems to me as if stackexchange would be a good place for them to host Questions & Answers regarding the software. I don't want UX.stackexchange to be come inundated with "how do I do x action in y software" sort of questions.

There are SE areas for power users etc... but perhaps an area that deals exclusively with photoshop, illustrator, axure, sketch-up, Premier, After Effects would be a good idea.
