Don't EVER put in image signatures. I'm begging you. Image signatures add absolutely nothing to the discussion. They just take up a bunch of room and serve to show off just how much people like their current pathetic attempt at photoshop skills. Avatars and user titles are just as dumb, but at least they don't stretch the page vertically like image signatures.
If you're really so bloody concerned with your precious signature, Ashrak, just put in an IMG tag at the bottom of each of your posts. Surely if you're so much damned better with computers than the rest of us as you seem to think, you can figure a way to do that.
