                    $this->set('message_id', $parent_id);
                    $this->set('message', $this->request->data['Message']['message']);
                    $this->Email->reset();
                    $this->Email->from = Configure::read('evento_settings.systemEmail');
                    $this->Email->to = $userTo['User']['username'].'  <'.$userTo['User']['email'].'>';
                    $this->Email->replyTo = Configure::read('evento_settings.systemEmail');
                    $this->Email->return = Configure::read('evento_settings.systemEmail');
