title: How to programmatically add, remove, or block people on Steam through a button
body: <p>There are many sites such as <a href="http://www.tf2outpost.com" rel="nofollow">www.tf2outpost.com</a> and <a href="http://www.bazaar.tf" rel="nofollow">www.bazaar.tf</a> where users can add other steam users through the click of a button. How exactly do you accomplish this? There's nothing in the web API that shows you how to add friends.</p>
  
  <p><strong>EDIT:</strong> I have found this code: <code>steam://friends/add/some_steam_id</code> Can you modify this code to block/remove people if you have their steam id?</p>
