I am trying to register an account but the system will not accept my Username.
This usually happens because you are trying to use a special character (such as $, *, @, etc) or a “space” (eg. ABCD 1234). Try again, making sure that only letters and numbers are used and there is no space between characters. It could also be the case that someone else has already registered with the same Username you are trying to create. If this happens please try and find another suitable Username.
