you could use a similar name without the character, or any other name. it's not actually tied to your account on the main site. lots of people use the same name in both places but i ended up going by "test" on the live, because by the time i thought to use the same name i was already known by test there lol
hung out on hextube https://live.hexbear.net/
i can't log in to hextube because i made a bad username with an illegal character so i have to log in with email but that's not an option on the live
