Your username can be just about anything you like. By default, it is set to your email address, but you can change it. It can include letters, numbers, spaces, and punctuation. The "case" of the letters in your username DOES NOT matter. If your username is or resembles an email address, it must be your own email address.
Your password can also be just about anything you like. By default, it is set to random letters and numbers, but you can change it. It can include letters, numbers, spaces, and punctuation. The "case" of the letters in your password DOES matter. A password must be at least 6 characters.
