1) If your username sucks, make your display name something memorable or clever. It doesn't have to be whatever claptrap the nest stuck you with. You can change it to something different from your username in "modify profile".
2) Give yourself a distinctive avatar or sig.
Give us a chance to get to know *you* - as an internetz person, not just a security code jumble :-)

Original message: It's a new board with almost unlimited name options. WTF are lurker people choosing little letter number combos? Do you hate the rest of us? Can't you think of a single clever or memorable name?
