Facebook has changed your email

FACEBOOK has changed your email settings while you slept. Here are a few
simple steps to restore your old, non-Facebook email address. Start by
visiting your profile page and clicking on "About" to bring up, amongst
other things, your contact info. Click the edit button on the "Contact Info"
section, which should bring up a list of all the email addresses Facebook
has on file for you, including your new facebook-domained email address.
Left click on the open circle to the right of your.name.here@facebook.com
and choose the "Hidden from Timeline" closed circle. Then pick which email
address you'd prefer folks to contact you at, and change that closed "Hidden
from Timeline" circle to an open "Shown on Timeline" circle. Simple as that!
