I can see it just fine as well. And I understand where you're coming from, Steve, but like has been brought up, I think we'd end up getting a lot of users asking why there's a little icon next to their name. Even if it didn't happen a lot, it would probably still be annoying. Heh.
Personally, I like the first image in evilfantasy's post (the blue fits in a lot better), but I think the text might look better white. Of course, I guess there isn't actually too much reason to use an image instead of text. But if we did use an image, that one would have my vote.
