The IRC Chat (Internet Relay Chat), is a fast and easy way to talk to fellow players in real time.|
You can use the WarOnline IRC-Chat page, which loads a Java-based IRC applet (which you must accept when it tries to install), as a quick and easy way to get into the IRC Chat.
Alternatively, you can download a full IRC-Chat client like mIRC.
