I am getting my first mac next week, and I have to simple questions that I think I may already know the answer to. First, does mail have to be running to alert you if you have a new message (I am sure it does)? Second, does ichat have to be running in order to accept a video chat or text chat? Will one still be alerted when someone wants to chat even if ichat is not running on your computer? Will you get a message telling you someone wishes to chat then have ichat automatically open? Or do both people have to have ichat running in order to attempt to communicate.
