If you want to change your e-mail address yourself, you can do so by clicking the User CP box in the upper right of the screen, the clicking on “edit profile” once that page downloads. Once in your profile, just swap e-mail addresses and click “submit,” and that should do the trick.
My fault for not re-reading the FAQ again. (My concern was whether your old email account had to be still working for you to make the switch.)
Now that the matter is solved, could a moderator please lock this thread? Thank you.
