title: ModX Revo: Get Current Webuser or Manager session
body: <p>How can I get the the number of all logged webuser (or manager, but not all types together). Is it possible with ModX API? Or is it necessary to inspect the DB table modx_session - but how is "data" column to readable?</p>
  
  <p>I want to show a user counter, who is online (like in a forum).</p>
