Just turn off signatures. They all look great to me now...
I may have to, but I hope it doesn't come to that. I want to be able to see what everyone has done or is up to. I just don't need honking great images that look like they've come from one of those teenage Photoshop forums where everyone has a 800x600 sig they designed themselves and every forum page is one page of text and fourteen pages of sigs. I'm fine with something small and tasteful like a little banner or button.
