Today, Facebook was kind enough to replace the e-mail account listed on your profile with the @Facebook.com e-mail address it provided you with awhile back. Wait, you didn't give Facebook permission to make the change? No one did. Not cool, Facebook.
Changing the e-mail account listed on your Facebook profile will only take a few minutes out of your day, but is well worth the time if you want people to know the best way to get in touch with you.
View your Facebook Timeline.
Click on your About section.
Click on Edit in the Contact Info section.
Next to your personal e-mail you should see a crossed out circle. Change that to the open circle, like the one next to your Facebook e-mail address. Then, if you don't want your Facebook e-mail listed, mark it as hidden from your Timeline.
Click on Save when you're finished.
Your proper e-mail listing should now be restored. Let's all hope Facebook doesn't decide to take it upon itself to make anymore changes without at least asking first.
