title: TightVNC: How to list all connected users
body: <p>I'm using TightVNC (Version 2.8.5) to connect to machines.
  While using it the clipboard between my Computer and the remote Computer is transfered in both directions. I need that function, so it's ok for me.
  Today I noticed that the clipboard changed (likely because another user also connected via TightVNC).<br>
  I didn't find a possibility to find out who connected or watched me - that's worrying me...</p>
  
  <p><b>How can I find out which other users</p>
  
  <ul>
  <li>are currently connected via TightVNC?</li>
  <li>were connected in the past? (Logfile)
  </b></li>
  </ul>
