How about adding a section dedicated to photoshopped images of chinese cars? I would be able to add a few images into that abit later if it was added to the forums. 4*real*Made_in_China is starting to use photoshop and im sure this would interest him as well.
Well Admin couldn't you make a new forum section on the main forum page similar to what you have done for "classifieds" and "other china motor vehicles"? Simply sticking it into the "Offtopic" forum as a subsection doesn't sound like a good idea in my opinion. Also you could allow drawings and sketches in this section as well in order to broaden its appeal.
