What is IRC?
Internet Relay Chat (IRC) is a form of instant communication over the Internet. It is mainly designed for group (many-to-many) communication in discussion forums called channels, but also allows one-to-one communication. IRC was created by Jarkko Oikarinen (nickname "WiZ") in late August 1988 to replace a program called MUT (MultiUser talk) on a BBS called OuluBox in Finland. Oikarinen found inspiration in Bitnet Relay Chat which operated on the Bitnet network. IRC gained prominence when it was used to report on the Soviet coup attempt of 1991 throughout a media blackout. It was previously used in a similar fashion by Kuwaitis during the Iraqi invasion. You need an IRC client now to connect to an IRC server, and give IRC a try. There are several clients available. what program you need depends on what Operating System you use.

What is a fanlisting?
A fanlisting is simply an online list of fans of a subject, such as a TV show, actor, or musician, that is created by an individual and open for fans from around the world to join. There are no costs, and the only requirements to join a fanlisting are your name and country. Fanlisting is a place where you can sign up with other fans. (description from The Fanlistings)

Why fanlisting for IRC?
Obviously you haven't tried it yet since you need to ask. ;) It's simply addicting way of communication.
