IRC (Internet Relay Chat) is a text-based chat medium. In short, it is the predecessor to instant messaging clients most people use today. Although somewhat antiquated, it is still in use and is a great alternative to proprietary and closed-off chat media. The Warehouse 13 Wiki has an unregistered channel on the FreeNode IRC network; for IRC-savvy users, simply join #warehouse13 on [irc://irc.freenode.net/#warehouse13 irc.freenode.net].
