I only make sigs for close friends (read: Artem and Willian are the only people I'll make a signature for aside from myself). Maybe the popular sig makers here should start doing the same.
Gauge, either stfu and wait or make your own. There is a shit load of people asking for sigs everyday. Just because you make a thread doesn't mean it will go any faster.
Open up Paintshop and make yourself something fancy. Like Myrrh said, you can't expect something from asking. It ain't definite. Just gotta accept it, dude.
