title: How to check permission for posting on group facebook
body: <p>I use FQL to retrieve the group list:</p>
  
  <pre><code>SELECT gid, name, privacy FROM group WHERE gid IN (SELECT gid FROM group_member WHERE uid=me())
  </code></pre>
  
  <p>When i tried post message in group wall (with the privacy is OPEN) but failed.</p>
  
  <p>And in <em>Group settings</em>, there is an option <em>Posting permissions</em>.</p>
  
  <p><a href="http://i.imgbox.com/adgtjrOK.jpg" rel="nofollow">http://i.imgbox.com/adgtjrOK.jpg</a></p>
  
  <p>So how do I get the <em>Posting permissions</em> before posting message.</p>
  
  <p>Please help me!</p>
