Travis, In your cpanel set your default address for the domain to send all your unrouted email (default email) to your gmail address. That way you can use anyaddress@yourdomain.com on the fly when having to complete a signup someplace and that anyaddress@yourdomain.com will route through to your gmail account. Then if you loose your gmail account you can change where your default unrouted email gets forwarded to. I do this for all my domains and have them all routed to the same gmail account.

Thank you for your contribution. I look forward to trying it on for size. ;)
