Also known as a user name, log-in name, member name, alias, or nickname. It should not be your real first and last name, but something made up that you can remember but that doesn't tell anyone else who you are in real life. Preferably, your screen name also doesn't let anyone know whether you're a boy or a girl. An example would be baseball123 or Poohbear. Your user name is your name on the Web. It hides your real identity.
