Guild Wars 2 Wiki:IRC
IRC (Internet Relay Chat) is a chat protocol that runs on independent server networks and requires no registration to use. Anyone can use the #gww channel on the GameSurge network to chat with Guild Wars Wiki and Guild Wars 2 Wiki users and administrators, players in general, and on occasion with ArenaNet's wiki liason Stephane Lo Presti as well.
Connecting to IRC
There are many web-based implementations of IRC chat clients available. A simple IRC chat widget is included here. Simply enter a nickname (use underscores instead of spaces) and click Connect.
Other IRC clients
Dedicated IRC clients, while less portable than browser-based solutions, offer additional features and convenience. There are many IRC clients available for every desktop and mobile operating system. Some popular multi-platform options include mIRC and HexChat (formerly XChat-WDK). An extensive list of IRC clients can be found on Wikipedia.
