As an experiment, I've allowed signatures on these forums. Images in them are NOT allowed; you may have up to 2 smilies and 2 URLs in them. Basically, think of them as text-only ads. Large picture spams are annoying on other boards, and if you can't make your point in text, you need to try again. Keep your signature to 5 or fewer lines, as well.
If these are abused, I'll yank the ability to have signatures -- first the abuser's abilities to have signatures, and globally if it gets that bad.
