How do most of you use Ichat? I'm new to the Mac, and I think I may be missing something. Right now I'm using it with AOL, but I was just reading about another IM program called Jabber. I don't know anything about this other service. I guess what I'm not understanding is do most Ichat users connect to Apple servers, or is Ichat just a front end to use AOL, Jabber and other services? I'd be interested to know how you are all using Ichat, how is Jabber different from AOL, and if you can set-up the client to use multiple services. Thanks everyone!!
