Chapter 20. iChat
Somewhere between email and the telephone lies the joyous communication tool called instant messaging. Plenty of instant messenger programs run on the Mac, but Mac OS X comes with its very own instant messenger program called iChat. It’s built right into the system and ready to connect to your friends on the Yahoo, AIM, Jabber, Facebook, or Google Talk networks.
To start up iChat, go to Applications→iChat, or just click iChat’s Dock icon. This chapter covers how to use iChat to communicate by video, audio, and text with your online pals.
