WordPress MU

ok what i am trying to do is get certain storys showing up from different blogs from the same site... I know how to get all the storys show up from the main page but not the others. I have tried many things and keep getting stuck.. is there a certain way to display the blogs?

ex
<?php query_posts('author=2&showposts=4'); ?>

Say if i don't want to pull in from the author but i want to pull in from the blog... a big reward if anyone can help me solve it.

You can use this code:

<?php
$domain = $wpdb->get_var( "SELECT domain FROM {$wpdb->blogs} WHERE blog_id=".$wpdb->blogid);

$posts = $wpdb->get_col( "SELECT ID FROM wp_".$wpdb->blogid."_posts WHERE guid like '%".$domain."%'");
foreach($posts as $p)
{
$postdetail=get_blog_post($wpdb->blogid,$p);
?>
<a href="<?php echo $postdetail->guid;?>"><?php echo $postdetail->post_title;?></a>;

<?php
}
?>

Above code shows current blog's posts,you can use any blog id to show posts of that blog in place of '$wpdb->blogid'.

Hope,it'll help you..
