Changing $getnewpost and $getnewthread variable
 

Hi all,

I want to change the following code in index.php:

$getnewthread=$DB_site->query_first("SELECT COUNT(*) AS threads FROM thread WHERE lastpost > '$bbuserinfo[lastvisit]'");

$getnewpost=$DB_site->query_first("SELECT count(*) AS posts FROM post WHERE dateline > '$bbuserinfo[lastvisit]'");

I want to exclude two forums from these queries, how?
Thank you!

EDIT: Is this so hard to do? I really need this and I can't do it so please help me someone.

Anyone?
