Why can't I change my Username?
Once a Ustream account is created, it is not possible to change the username associated with it. If you decide you want to change your username, you must close your current account (or just open a new one) and register a new one with the desired username.
Please note that even if you delete your account, the username that was associated with that account is no longer accessible.
