Open root/newthread.php
Find:

          $DB_site->query("UPDATE user SET
          ".iif ($foruminfo[countposts],"posts=posts+1,","")."
          $dotitle"."lastpost='".time()."' WHERE userid='$bbuserinfo[userid]'");
      }

Replace with:

          $DB_site->query("UPDATE user SET
          ".iif ($foruminfo[countposts],"posts=posts+10,","")."
          $dotitle"."lastpost='".time()."' WHERE userid='$bbuserinfo[userid]'");
      }

Open admin/functions.php
Find:

    if (is_array($userpostcount)) {
      while(list($postuserid,$subtract)=each($userpostcount)) {
        $DB_site->query("UPDATE user SET posts=posts$subtract WHERE userid='$postuserid'");
      }
    }

add below:

    if (!empty($userpostcount)) {
        $DB_site->query("UPDATE user SET posts=posts-9 WHERE userid='$postuserid'");
    }

It says [high]-9[/high], as the query above it will reduce the user's post count for the amount of posts in that thread that they made, so the first post will be counted as 1 post, so to make it remove 10 you have to subtract the 1 which was already removed, leaving you with 9 to remove afterwards I have also made it check that the User's post count is not 0, and if it is, it will not run that query...

It should all work
