I got bored and thought I'd make a sig for Joel on my laptop which has no fonts on it whatsoever so it turned out like this:

Edit by Joel: Cheers, thanks. Pretty cool but I prefer not to have a graphical signature. Still, nice effort.

EDIT:
On behalf of myself I'd like to uhh... say that I'm a bit busy and I haven't been browsing these forums lately, so I don't think I'll be making any signatures in the near future. There are some other graphic wizards on the forums so I bet you could ask them
