You can have instant message sessions with several different people at once, each in its own window. Or, you can include multiple people in the same session by starting a chat and inviting all the buddies you want to participate.
You can use iChat AV to communicate with people who use Mac.com or AIM screen names. If your friends are using older versions of the AIM software, they might need to get a newer version of the AIM software in order to send messages to your Mac.com screen name, or to see when you are online. |
