title: access token expiration/renewal
body: <p>I have a personal website on which i want to display my latest facebook comment. Everything works fine, but I'm not sure how the access token expiration works. I have a two months access token, so does it mean that every two months I have to get a new access token and replace the one in my code. If so, it's really not convenient at all... especially since all this is to authorize MYSELF to get my OWN comments.</p>
  
  <p>Is there a way to automatically renew the access token or to get a token that doesn't expire or any other way around this two months expiration thing?</p>
