most of the time i think usernames are important, but it's a smut game and those usually value privacy and anonymity options for the players (even encouraging alts and socks for the players). so i don't think it's a surprise that they wouldn't put as much emphasis on the usernames because they aren't as important.

if you are that hung up you can hover to see it or if you're in the game you can check out their preference list, but it's not a big need. everything you need to know (character name, canon, which wing they are) as potential player is there and if you are a player in the game you have access to more info. the privacy the current list provides to the players is a plus.
