I should be able to update your email address for you, but I’d need to be able to locate the account. Do you happen to have a link to the old account? Or perhaps you can give me the defunct emails to check?
As far as the new email address, I would strongly recommend emailing that to me at tos_team@adult-fanfiction.org. We know the forums are public, and spammers scrape email addresses, so this is for your privacy.
