Facebook - email addresses and face recognition

Email addresses - Facebook has changed yours to be <something>@facebook.com
Facebook recently made some changes to change your primary email address to be <yourname>@facebook.com, and relegated your normal email address down the list.  It also made this new facebook.com email address visible on your profile to everyone. The problem with this is that if any of your friends with smartphones synchronise their smartphone addressbooks with facebook, this will mean that they now have the new @facebook.com email address for you, instead of your real email address. Not great.
 
Here's how to get rid of the @facebook.com email address from your profile.

• Click on the "About" tab on your profile
• Go to the section marked "Contact info" and click"Edit"

• Click the padlock to change the settings on each email address to specify if it is displayed on your profile or not, and who can see it.
• Press "Save".

Stop Facebook from suggesting your name as appearing in others' photos

• Go to your Facebook account's privacy settings. https://www.facebook.com/settings/?tab=privacy
• Go to "Timeline and tagging" and click on "Edit settings".
• Choose "Who sees tag suggestions when photos that look like you are uploaded?".
• Select "No one" if you don't want Facebook to tell your friends when it has recognised your face in a photo they have uploaded
• Press "OK".
