When you delete your Facebook account, no one can see it unless you login to it again.
no just the one you choose to delete
You cannot completely clear your facebook login email that is registered with your account. However, you can restrict your friends and other people from seeing your email address via privacy settings.
You put your curser over the email you want to delete and press the delete button on your keyboard.
There isn't a way to retrieve your email you registered with, The best advice i can give you is to check all your email acounts (if you don't delete your emails) and search for "Facebook" and it should come up with any emails you get from facebook (including a registration email from facebook).
To delete emails from the sign in box, just select the emails that you want to delete and press the delete sign.
Login to your Facebook account. Click Profile button and then Photos tab. Click on a picture that you want to delete or click on a album that contains that photo and find it and click on the photo. When you see the magnified photo, scroll down and click on "Delete This Photo".
you look up the person and click report abuse.
press up, up, up, left, down, down, down, left, right, then click 'delete account'
Apparently, the Facebook account deletion process is straightforward. All you need to do is simply, login to your Facebook account, then click Settings and from the Deactivate section choose Deactivate.The above process only deactivates the account but does not delete it completely... If you want to delete the account completely, you will have to get in touch with Facebook via email and request that they delete the account permanently.
