	$f = create_function('$a,$b','return strcasecmp($a->blogname,$b->blogname);');
	uasort($blogs, $f);
	return $blogs;
}
add_filter('get_blogs_of_user', 'dccf_sort_my_sites');

		return;
	$wp_admin_bar->add_menu(array(
		'id' => 'editorial_calendar_link',
		'title' => __('Editorial Calendar'),
		'href' => __('http://' . strtolower($_SERVER['HTTP_HOST']) . '/wp-admin/edit.php?page=cal'),
