How do I get an iChat “account”?
You can use your existing MobileMe (.Mac) account ID or an AIM account ID. If you don’t have either, sign up for a trial MobileMe account, or an AIM account. iChat works great for text chats. How do I use iChat for audio or video chats in Mac OS X 10.3? All you have to do is make sure your computer meets the iChat AV system requirements. If so, and if you have Mac OS X 10.3 Panther, it’s real easy to “turn” iChat into iChat AV–just plug in an iSight camera. Or, you can use a microphone and third-party FireWire (DV) camera that works with iChat and Mac OS X.
