wp_page_menu help

Hello I hope some can help, I am running a site,within that site, there is a tab for member content that is only viewable when the user is logged in, the member content page is is parent to various pages, that can be created and assigned via the wordpress interface. Hoever I also need to add 3 buddypress pages, theses are forums, groups and members. How would I assign these pages to a child of ‘Member Content’

Currently I build my nav like this,

<?php
				if(!is_user_logged_in()) {
					wp_page_menu('show_home=1&exclude=214&exclude_tree=80');
				} else {
					wp_page_menu('show_home=1&exclude=214');
				}
			?>
