I think as far as usernames go on Transformice, we're pretty limited. I say instead of 12 possible characters, raise it up to about 15-18 more.
I believe Transformice is adding a username change function soon so if it were implemented with that update, it would be pretty great.

i could actually try to make a username like " Alertalertyourphoneisbeeping " and it'd fit

According to an update from the admins, here, they'll be adding underscores "_" soon. They've already added numbers which was desperately needed to keep username originality going but I wouldn't mind being able to capitalize (or at least have a limit to what you can capitalize) but thats all. Having usernames such as "x0X-BOX_K1NG_77868865-0x" is really just plain ugly to look at.

Seems how the underscores are already coming out, /nosupport to anything other
