title: Being a member of a Facebook group and THEN to be able to register and login to a website. How to do it?
body: <p>I've been searching the internet for a while to come up with a solution for the issue of logging in to a website with the support of Facebook account. The case study is as follows:</p>
  
  <ol>
  <li>I have a website which provides course materials to my students in a class.</li>
  <li>I have created a Facebook Group - private - to keep in touch with only students who are registered for the course.</li>
  <li>I'd like to allow students to use their Facebook account (whom are member of that particular group) to be able to login to that website. This means public users with Facebook account which are not a member of that particular Facebook group should not able to login to that website.</li>
  <li>I've been using classic ASP for the development of that website, which provides teaching materials.</li>
  </ol>
