I can't register.

If you are unable to register, it could be due to one of the following reasons:

You have chosen an invalid password. When registering, your password must comply with the following rules: It must be at least 10 characters long and contain at least one capital letter and one special character (for example “!” or “%”). Your password must not contain your pseudonym or e-mail address.
You have chosen an invalid abbreviation. Your abbreviation must not contain spaces or special characters (for example “!” or “%”).
Your passwords don't match When registering, you must enter the same password twice in a row, which can sometimes fail. Try again.
Your e-mail address has already been used. This means that an account has already been created with that email address. If it's your own account, reset your password instead of registering again.
