1- make it a php file (rename it as index.php)
2- add:

PHP Code:

<?php require('boardurl/global.php'); ?>

in the begining of this file..

3- before ?> part you can query the db to get pms

PHP Code:

if ($bbuserinfo[userid]>=1)
{
$ignoreusers="";
  if (trim($bbuserinfo['ignorelist'])!="") {
    $ignoreusers='AND fromuserid<>'.implode(' AND fromuserid<>',explode(' ', trim($bbuserinfo['ignorelist'])));
  }
$allpm=$DB_site->query_first("SELECT COUNT(*) AS messages FROM privatemessage WHERE userid=$bbuserinfo[userid] $ignoreusers");
  $newpm=$DB_site->query_first("SELECT COUNT(*) AS messages FROM privatemessage WHERE userid=$bbuserinfo[userid] AND dateline>$bbuserinfo[lastvisit] AND folderid=0 $ignoreusers");
  $unreadpm=$DB_site->query_first("SELECT COUNT(*) AS messages FROM privatemessage WHERE userid=$bbuserinfo[userid] AND messageread=0 AND folderid=0 $ignoreusers");
} 


Now you can use variables ($unreadpm, $newpm, $allpm) to refer main page visitor's pms if he is a member..

Well this is basically the structure you need but a little bit PHP knowledge to apply will help a lot..
