Re: How to: Add a new menu section
create a file called new-menu-item.php and put it in your mu-plugins folder then add this code to your file:
<?php
function add_test_to_main_menu() {
echo '<li <a href="http://yoursite.com/Url-of-test/">Test</a></li>';
}
add_action('bp_nav_items', 'add_test_to_main_menu');
?>
