title: Facebook API Mutual Friends Count (Count Only)
body: <p>I would like to show mutual friends (Just a number X mutual friends - no other information) on a users profile who has signed up in an app I am working on.</p>
  
  <p>We had planned to do this using the list of friends ID's however this is now not accessible since Facebook updated it's permissions around this.</p>
  
  <p>Is there any way to do this now? I was looking at taggable_friends, would we be able to use this for that.</p>
  
  <p>Thankyou</p>
