Here is the SIG POLICY from the gaming clan I belong to that can give you ideas for this site. We were having issues with very BIG SIGs that took up more space than the actual text the member wrote and we also were having issue with some XXX rated SIGs. Our clan is family oriented and porn is not allowed in our forums. (ww.taw.net).
