  #   cmd.invoke( context, argString )
  # where 'context' is a MUES::Command::Context object, and argString is the
  # text of the command entered, with the command name and any leading/trailing
  # whitespace removed.

                  return [MUES::OutputEvent::new( "No such user '#{username}'\n\n" )]
          elsif !user.activated?
                  return [MUES::OutputEvent::new( "User '#{username}' doesn't appear to be logged in.\n\n" )]
          end
  else
          return [MUES::OutputEvent.new( self.usage )]
