Open your current e-mail address, go to the "Contacts" menu and select "Save instant messaging contacts..." and save them to disc.  Make a new e-mail address, sign in, and go to the "Contacts" menu and select "Import instant messaging contacts..." then navigate to the place where you saved your instant messaging contacts. There you go, you have your contacts in your new e-mail. It will take a bit of time for all of them to add you to their lists, though, so you'll have to wait.
