My Preferences > Email > E-mail address.

E-mail is only really used for notifications or account-related issues. I've got all notifications turned off but it helps to use an active e-mail address in case of needing to change your password.

You'll need to re-confirm your e-mail address when you change it. Also when you log in to your account you can log in with your user handle.
