WPMU Power Tools

I read about a plugin for WPMU, yes WPMU, that also works with Multisite 3.0+ so far to clean up old spam blogs, users, posts and comments. It was called WPMU Power Tools by Paid To Blog but it has since vanished from the web, but I managed to find a copy.

Code is below, it needs activating per site instead of network wide, I have just activated it on the primary blog.

user_login.'<br>';
}
 
//Migrate all users of one wordpress theme to another one
$old_theme = get_option('current_theme');
if($old_theme == 'Old Theme Name')
update_option('current_theme', 'New Theme Name');
 
//For Donncha's Sitewide Tags plugin: Populate tags blog with all posts made before the plugin was added
$posts = $wpdb->get_col( "SELECT ID FROM $wpdb->posts WHERE post_status = 'publish'" );
if ( !empty($posts) ) {
    foreach ( $posts as $post ) {
        $post_id = $post['ID'];
        if($post_id != 1 && $post_id != 2)
            sitewide_tags_post($post_id, get_post($post_id));
    }
}
