Actullay, it's just what I've been using at the other two forums I go to.
My avator is Rukifellth, also known as The Dark Messenger, of Bomberman 64 TSA! fame. He happens to be among some of my favorite video game characters ever.
My signature is composed of two pictures. The first one is Sigma from Megaman Xtreme 1, saying a Megaman Xtreme 2 quote that he actullay said. Shows ethier how lazy Capcom's translators are, or that Sigma is getting more and more insane each time we see him.
My second picture is Wario from the terrible Wario Blast comemrail, complete with his creepy-as-hell grin!
