WordPress MU

I'm needing to modify themes so that they display only one category of posts (cat 1) on the front page for all my users (reasons here).

I'd been using

if (is_home()) { query_posts("cat=1"); }

<?php if ($posts) {

[aside stuff here, it looks like]

foreach($posts as $post)
{
start_wp();
?>
<?php if ( in_category($AsideId) && !is_single() ) : ?>
<ul class="asides">
<li id="p<?php the_ID(); ?>">
<?php echo wptexturize($post->post_content); ?>
<br/>
<?php comments_popup_link('(0)', '(1)','(%)')?>  | <a href="<?php the_permalink(); ?>" title="Permalink: <?php echo wptexturize(strip_tags(stripslashes($post->post_title), '')); ?>" rel="bookmark">#</a> <?php edit_post_link('(edit)'); ?>
</li>
</ul>
<?php else: // If it's a regular post or a permalink page ?>
<div class="post" id="post-<?php the_ID(); ?>">
<div class="posttitle">
[...and we're off with the regular post code...]

Could anyone show me where I need to bust into that with my 'Hey, only show posts from one category if it's the Home page' code? Or do I need to do it some other way?

first thing that comes to my mind would be using a plugin that restricts which cats posts are shown on the frontpage. there are plenty of those around here...

Gotcha. I had tried the Front Page Excluded Categories plugin in mu-plugins without any luck, but switching that out, and using Front Page Cats instead does the trick... that one was just a little harder to track down, for some reason.

Thanks!
