I created my account over a decade ago when it seemed using Facebook logins for everything would be useful, HA. Now I'm trying to switch to logging in via username/email and password, but I don't have a current password (that I know of), and my email address is some generic fb_[numbers]@flyertalk.com address that I don't have access to.

I'm assuming I need:
1) an admin to manually update my email
2) go through the password recovery process to set a password
3) de-link facebook

So I'm posting here looking for help with #1, but also figured it'd be a good FAQ for others in similar situations.
