Forcing comments to the main blog

I use the following function in the theme’s functions.php to correct the comment count on my Sitewide Tags blog.

function ds_sitewide_tags_get_comments_num($count) {
  global $blog_id, $wpdb, $post;
  	$tags_blog_id = get_site_option( 'tags_blog_id' );
  	if( !$tags_blog_id || $blog_id != $tags_blog_id ) return $count;
  	list( $post_blog_id, $post_id ) = explode( '.', $post->guid );
  	$base = $wpdb->get_blog_prefix( $post_blog_id );
  	$r = $wpdb->get_col( "SELECT comment_count FROM {$base}posts WHERE ID=$post_id" );
 	if( is_array( $r ) ) return $r[0] + $count;
  return $count;
}
add_filter('get_comments_number', 'ds_sitewide_tags_get_comments_num');

Now, that doesn’t get the actual comments to the main blog, but I don’t need them to. Any post link on the main blog takes reader to the original blog where the comments show normally.

I use a comment indexer(in mu-plugins) that dupes every comment in the network into its own site_comments table: http://pastebin.com/DDvbJFDb

Add to the comment indexer a function to display the comments: http://pastebin.com/qa1L47ky

Then I need only the following snippet anywhere in the network in any theme to show a list of recent comments collected from every post and every site:

<?php
 display_recent_comments(10,150,'<ul>','</ul>','<li>','</li>');
?>

David –

Do I just copy and past the code from the first pastebin link into a new php file? Is there more to it?

Also, where in my theme should I put:

<?php
 display_recent_comments(10,150,'<ul>','</ul>','<li>','</li>');
?>

Thanks, very much, in advance.
