Thanks for the response!
I went to the link you provided and did the "add a pop account" but I'm not sure how to do the "add a forwarding address part." Do I even need to do that if I already added the pop account?
And also just to clarify, once my provider terminates the service no mail will be able to be sent to or from that address? There isn't a way to make it so if someone didn't get my new g-mail address, and sent it to my old one, it would be forwarded instead to the g-mail?
Sorry for all the questions, e-mail is one thing I'm not very savvy with!
