That's a player choice thing.

If you wish to go nameless (for now; there's no risk/chance of having your name unrevealed throughout), an epithet of some kind would be useful as a narrative nickname, as it were.

Character pictures are also optional, though, if you do use one, I'd rather you use the one from the character tab. I kinda made the Cast thing to look like a board game like Cluedo (or Clue, as Americans call it), so it'd tickle my pickle to see the board game 'pieces' being used.
