Icon Next to Name?

Some of you have cool photos/art next to your names when you post and respond to posts. I've been poking around the settings looking for how you set that and haven't had any luck! What do I do? I must have teh arts!!

WFG uses Gravatars -- see gravatar.com. Make sure you use the same email account as you signed up with here.

I love Gravatar. (I figure mine is working as well.) They're a fairly excellent way to keep a consistent face on blogs without having to produce some sort of OpenID system or etc. Of course, anyone who knows my e-mail can mimic my icon, but it's really just personalization not identification to me.
