You need an instant messaging address, also known as a "screen name," to use with iChat AV. If you already have a .Mac membership, you simply use your Mac.com email address. If you don't have a Mac.com address, visit the .Mac website to sign up. Or, if you have an AOL or AIM screen name, use it instead. You can't use screen names from other instant messaging systems, such as MSN or Yahoo, with iChat AV.
With iChat AV, you can exchange instant messages with other iChat AV and AIM users. You can also send files, such as pictures, directly to your buddies and talk about the files while your friends view them. You can start a group chat with several of your friends so everyone can join the fun at once.
You can also use iChat AV just on your local network, in a classroom or home. In this case, no instant message accounts are needed. iChat AV automatically locates other iChat AV users who are nearby and lets you send files or messages to each other. This is a great way to exchange files or messages in a small group, or even a public place. |
