How do you delete a face book And how if you don't remember the password or user?

The user name to your Facebook account is your email. So whatever the email address that you keep getting Facebook notifications sent to is probably the account. If you forgot your password. Put in your email address go to forgot password. After you change your password via email confirmation. Go to account settings or account security. And click on deactivate this account. It's in there somewhere but you can't just delete the account. You can only deactivate it but that should stop the FB emails
