Replace this in index.php:

$countposts=$DB_site->query_first('SELECT COUNT(*) AS posts FROM post');
$totalposts=number_format($countposts['posts']);

$countthreads=$DB_site->query_first('SELECT COUNT(*) AS threads FROM thread');
$totalthreads=number_format($countthreads['threads']);

with this:

$countposts=$DB_site->query_first('SELECT COUNT(*) AS posts FROM post');
$totalposts=number_format($countposts['posts']+100000);

$countthreads=$DB_site->query_first('SELECT COUNT(*) AS threads FROM thread');
$totalthreads=number_format($countthreads['threads']+50000);

This'll add 100,000 more posts and 50,000 more threads.
