Ok - Chris, you've just been promoted to the position of Chief Executive Operational Presidental Officer of, um, er, ahh... Aw hell. How about the Name Tag Dude! Yeah! That's it! You're the new NTD. (Surprise!)
Seriously though, we did talk about name tags last year. Though your idea to include both the screen name and the avatar is genius! Run with it pal... I like the idea a lot.
