You're required to choose a shell account name. It must start with a-z, and can only contain lowercase a-z, 0-9, and - characters.

• If you already had a SVN account with the same username, ask it to be created manually and include this information.
• If that's not the case, ask someone to verify from a labs instance whether the shell username is taken, by issuing the command groups $username on a shell.
