Changing your username
Sometimes, you'll want to change your username from the one you originally registered. Perhaps, you registered with something regarding a team, but that sentiment is no longer relevant. Maybe you registered with your name, but now want a moniker. Whatever the reason, you can change your username. Both previous and future messages will be listed under the new name.
To change your username, Go to UserCP. Then, under the menu heading Your Profile, select the option "Change Username." It will then prompt you for your password and your preferred new user name. Enter both, and you'll now have your new CardBoard identity.
