I understand from what I read on the web that one way to get a google voice invite is to use a .edu email address. My question is this, does the account have to stay with the .edu address once you receive the invite and sign up? Or can it be transferred? I have access to a .edu address but don't really want to use it for google voice permanently. Also if you sign up using a .edu address do you get invitations to send to other people?
