You all really need to set an avatar in your account settings. That way the forums feel more homely and have some personality. My other ulterior motive is that I need sparklies to look at while I'm on the site and being bored :)

When you're logged in just click "my account" and then on that page hit "edit". At the bottom of the main edit page there's a "Pictures" section where you can upload an 80x80 (or less) picture for an avatar. I set it to 80x80 so that it'll still fit in the little message box when you make a one-line forum post.
