The name your server shows in the in-game server browser. Keep it to 16 characters or fewer -- the browser cuts off anything longer, so make the first 16 characters count. You can change it later from your server's Startup tab.

Optional. Found in-game under Settings, bottom-left ("My Player ID") -- a 32-character code, not your Steam name or character name. Supply it here and your world is ready to play the moment the server finishes setting up. Leave it blank and you can add it yourself later under your server's Startup tab, then restart -- your world is only created once an owner is set.
