title: Accessing a common Facebook account. Facebook authentication and access tokens
body: <p>I'd want to allow all users of a mobile app to post to a same Facebook account, account whose credentials I don't want them to know... I'd simply want to make it transparent to users, I mean, I'd like to show users an app dialog where they could write a message and post it to a certain Facebook account, and let users know they are posting to a certain account, but I dont want them to know the credentials of such account and have to login on it.</p>
  
  <p>So, firstly, I need to avoid the Facebook's login dialog being displayed to my users. As far as I know, it is possible to skip the login dialog step if you already have an access token. On the other hand, it seems that an access token identifies a user... then, could a same access token be used by several users? I guess that, at server-side, that would be as receiving requests from an only user, but is there any problem in that?</p>
  
  <p>Has somebody faced a similar scenario?</p>
  
  <p>Thanks!</p>
