IRC

IRC is short for Internet Relay Chat, a communication protocol that allows users to send messages to each other.

To join a IRC server, a user must connect to a server address that's given on the tracker (usually given in the trackers wiki pages.) Once connected to the server, a channel must be joined, a room/lobby where users all join and can talk amongst each other. Sending direct messages is also possible through IRC.
