Wow that's got a lot of potential. Not only because there are a lot of designers out there, but I bet when they are looking for a good forum, the first thing they'd think to search would be "design forums" itself. My estimate would be low XXXX, I could be wrong though .
Huge potential. The domain name along, as said above, is worth quite a bit. Personally, I'd develope it.
thankya ! i was confused that the reveiws were for design forums or designsforum i suppose developing it would be the best idea for now
