—, 350 rep isn't that much and you will get it eventually, most people didn't complain when we didn't have a signature for the last few weeks so I don't think it's that big a problem. It really should help deter spammers as well, along with the rep required for a URL in your profile (we have a lot of spammers already signing up just to post URLs in their profile). I want to try really hard to keep this website spam free, and 350 rep for a forum signature is perfectly reasonable I think :)
sved yes I plan to do this at some point, but we change it all quite frequently, when it's more fixed in place I will do a list!
