you could only be either guests, or members.... Maybe.. Unregistered members!.. Wait!--If your'e not registered, you're a guest.... Or Banned Members?- But they're still members arent they?!?!!?
Well, An Anonmous member is a member who has logged on, But clicks the "privacy" button, so they can't be seen on the active users list, but are shown as a "Anonymouse user".
