A gif for a signature or avatar? If I can get the video I'll have a go but 9 seconds is going to make a big file, too big for avatar use. Also we have a separate thread for avatar requests.
Edit: That's 5.5MB fucking Megabytes!
Signatures: They shall be no taller than 175 pixels INCLUDING text, if you don't want a picture then it's like 5 lines of text, no wider than 600 pixels and may not contain nudity (tits and stuff from down south). Must NOT induce epileptic seizures (repetitive, flashing patterns). The filesize must be less than about 100KB -- that means no 3 megabyte animations!
