I have a couple of questions regarding the iChat. When signing up for the first time, do I just go directly into iChat? Should I have either a Googletalk or Yahoo Instant Messenger set up ahead of time and then sign into Apple iChat? Also, somebody recommended that I use "Adium" instant messaging because it is compatible with all the different Instant Messaging Services. I guess what I am asking for is a few get started pointers. Thank you!
