=Using iChat to collaborate with your team= All of the screen shots below come from the apple help menu

You use iChat to send “instant messages” to friends and family when they’re online. Your instant message appears in a window on your friend’s screen almost as soon as you send it. Unlike an email message, you don’t have to wait for your instant message to be sent and retrieved; your friend sees it immediately and can respond right away. You can also send files across the Internet or to others on your local network.

With iChat, you can audio and video conference with a group of people at the same time, to keep in touch with friends, family, and colleagues around the world.

For more information, open iChat and choose Help > iChat Help.
