How to customize menu in BP Social?

Hi, I am new to BP Social theme and was wondering what is the best way to customize the main menu. It seems that the menu is organized by listing "Home", "Activity", and "Community" followed by all the pages in the alphabetical order. What is the best way to reorganize the menu items or exclude some of them? In BP default theme I did this by editing the line in header.php
<?php wp_list_pages( 'title_li=&depth=1&exclude=7,11,' . bp_dtheme_page_on_front() ); ?>
So far I could not figure out an easy way to do this in BP Social. Also, is there a way to do this from a dashboard? I use BP 1.2.8 and WP 3.1, the site is
