What is a fanlisting?
According to Fanlistings.org, a fanlisting is a web clique that lists fans of a particular subject, in this case Yuber. Unlike most web cliques, a person does not need a web site in order to join. Fans from around the world submit their information and are then listed to show their love for the subject.

Who the heck is Yuber?
A Black Knight/demon from a game series called Suikoden. There's also a manga version of Suikoden III which he appears in. Take a look around the main website the fanlisting is part of; there should be plenty of more information available.

How do I join?
Fill out the joining form, of course. If the form doesn't work for you, read the information for other ways to join.
