Only the live.com one but i heard only gmail works
someone said yahoo and gmail work good. i think someone else said if you change your username, it will send you a code to the new one to activate but maybe someone should confirm that. they talked about it a few pages back
just incase when we get transfer they may send info the email we made our accounts with, since that email is from 9 years ago and probably won't even work anymore I wanted to put my everyday one there just incase.
