not tested but i think it should do what ya want:

in newreply.php find:

PHP Code:

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


replace it with:

PHP Code:

if((time()-$bbuserinfo[lastpost])<=90) {
$DB_site->query("UPDATE user SET
          posts=posts-1, lastpost='".time()."' WHERE userid='$bbuserinfo[userid]'");
} else {          $DB_site->query("UPDATE user SET
          ".iif ($foruminfo[countposts],"posts=posts+1,","")."
          $dotitle"."lastpost='".time()."' WHERE userid='$bbuserinfo[userid]'");
}
