title: Like facebook page when login with facebook
body: <p>I'm using facebook login on my webpage.
  At first login the facebook login app ask for permission to get user data.</p>
  
  <p>There is any way to improve this to ask for permission of liking my facebook page too?
  And after user clicks, he would also like my facebook page.</p>
  
  <p>Edit:
  My goal is to force people to like my facebook page if they want to login with facebook account to my page (not regular registration). For sure I would ask for permission to not violate terms of use. But would be nice if when they click on login and giving permission they would also like my fb page. So Facebook login and like wouldn't be seperated.</p>
