Do not want to display blog entries for one category

Hi there,

My main index file has this code :

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div class=”post” id=”post-<?php the_ID(); ?>”>
<h2>” rel=”bookmark” title=”Permanent Link to <?php the_title(); ?>”><?php the_title(); ?></h2>
<div class=”postinfo”>
By <?php the_author_posts_link(); ?> on <?php the_time(‘M j, Y’) ?> in <?php the_category(‘, ‘); ?> | <?php comments_popup_link(‘comments(0)’, ‘comments(1)’, ‘comments(%)’); ?>
</div>
<div class=”entry”>
<?php the_content(‘Read the full article’); ?>
<?php if ( function_exists(‘the_tags’) ) : ?>
<div class=”tags”><?php the_tags(); ?></div>
<?php endif; ?>
</div>
<div style=”clear:both;”></div>
</div>

<?php endwhile; endif; ?>

and it displays all blog entries from all categories on the main page.
But I do not want to display the blog entries that belong to one specific category called “Quickie”.
How do I change the code to do that?

Thanks,
dshooter
