 * This timer task updates the  {@link ChatState} to set the status to logged on if the

 * <p>This must be delayed, as the initial chat state (like current users and topic) should have time to
 * be initialized before logon is set as completed. After logon is set as completed then all changes
 * to users are treated as regular events, like topic changed, user logged on, and more.</p>
