Signatures end up being abused and also make the forum perform slower (when people decide to start taking the piss with 900 images of 900x900px) We have a large community here and performance of the site is paramount, if I did enable it and in a few months/years time it starts slowing the site down (which is currently rapid), who do you think the first people to moan about it are? Yes, you guessed it, the same people who asked for signatures in the first place. At this moment in time, the answer is no.
