Firstly, I want to say that I don't know how to edit it, but, yes, in functions_online.php you can check this part of code:

        case 'pm':
            $userinfo['action'] = $vbphrase['private_messaging'];
            if ($vbulletin->userinfo['permissions']['wolpermissions'] & $vbulletin->bf_ugp_wolpermissions['canwhosonlinefull'])
            {
                if ($seeuserid)
                {
                    $userinfo['where'] = '<a href="member.php?' . $vbulletin->session->vars['sessionurl'] . "u=$seeuserid\">$wol_user[$seeuserid]</a>";
                }
                if ($userinfo['values']['do'] == 'newpm' OR $userinfo['values']['do'] == 'insertpm' OR $userinfo['values']['do'] == 'newmessage')
                {
                    $userinfo['action'] = $vbphrase['creating_private_message'];
                }
                else if ($userinfo['values']['do'] == 'editfolders' OR $userinfo['action']['do'] == 'updatefolders')
                {
                    $userinfo['action'] = $vbphrase['modifying_private_message_folders'];
                }
                else if ($userinfo['values']['do'] == 'trackpm' OR $userinfo['values']['do'] == 'deletepmreceipt')
                {
                    $userinfo['action'] = $vbphrase['tracking_private_messages'];
                }
                else if ($userinfo['values']['do'] == 'showpm')
                {
                    $userinfo['action'] = $vbphrase['viewing_private_message'];
                }
                else if ($userinfo['values']['do'] == 'downloadpm')
                {
                    $userinfo['action'] = $vbphrase['downloading_private_messages'];
                }

            }
            break;
