exclude blog page category

[s2aebelt]

first off. great theme! i am almost ready to switch over from my original theme. i found the coding to show all blog posts on the blog page, now I am hoping there is a way to EXCLUDE a category from the all blog posts code.

Here is the code I grabbed from the forum.

<?php $page = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("showposts=".$blog_cat_1_num."&paged=$page"); while ( have_posts() ) : the_post() ?>

i need to exclude the Tutorial Posts (cat id 5) from appearing on the blog page. http://brandbuildsell.com/v3/?page_id=49

thanks in advance!
