We strongly suggest that you choose a username that is not easily guessable and one that is NOT based on your own actual name. This is to improve the security of your account, as a casual hacker would need to find out both the username AND the password too to get into your account. If you had used a username based on your actual name, that part would be easy for the hacker.
Username should not be less than 4 characters or more than 25.
Our server will check if this username was already in use. If so, you would get an error message accordingly.
