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.

If you are not familiar about what IRC is, then I would suggest you read the Intro to IRC on the mIRC homepage. If you are already well acquainted with IRC and you are looking for a comprehensive-commands-guide, then you can also checkout the IRC command list also found on the mIRC homepage.
