So If I click on system prefs/users & groups, under my account, my appleID is listed as my email address which is <myemail>@hotmail.com. Fair enough. So I guess the means my AppleID is just that. However, when I go to system prefs/icloud, my account is listed as <myself>@me.com. Now I'm confused. I understand that the the me.com is an entirely separate email account but, I don't even know how I got it. Should I be using THAT as my appleID?
