Send in an e-mail to [email protected] with the name of the account you're requesting access to as well as the email that you don't have access to anymore. Be sure to include an email address that you DO have control of that you want the account's associated email address to be changed to.

Lummox JR will be able to sort you out there when he has a spare moment.
