Good question. I have never figured out how to do that myself. I've always wanted to change my email on my Facebook page and never knew how to go about it. Instead, I would just create a whole new Facebook account with the email I wanted. That's a lot of work because I lose all my post and have to repost them and send all my friends from my old list friend request all over again. So if anyone has the answers about how to change a facebook email without creating a whole other account, that would be amazing to me as well. Honestly, I always thought I was the only one who wanted to do something like that. Hope it's possible and that someone out there has the answer.
