Title says it all. Is there any way to delete a username from the game? I can't use the username I originally inputted as it registers as created even before email confirmation (that is a bad idea, by the way), and I didn't get the confirmation email, either because I misspelled my email or it was autodeleted by the spam filter or some other factor. Since the game has no option to resend the confirmation email, I'm hoping that I could just get the username SenseiMewtwo12345 removed from the system so that I can re-create it.
