Your username should be between 6 and 16 characters with no special characters (ex. #, !, or &), cannot be your first or last name, and must be unique in our system. Your password should be at least 8 characters and must include a combination of uppercase and lowercase letters, numbers, and special characters. The email address you enter should include the @ sign, should be valid, and must also be unique in our system—only one user account can be tied to a given email address.
