Avatars are now enabled in the forums. Donors should be able to add them in their preferences and they'll show up on their forum posts. Inappropriate images will be deleted. And images in forum signatures will be disabled soon.
Brad has FINALLY gotten around to letting us see our avatars. It was only a matter of time, but I welcome it with as much enthusiasm as people who liked these two things welcomed it-Star Wars III, and Harry Potter and the Half-Blood Prince.
