For others who are frustrated by add_submenu_page – using WPMU2.9.1 BP1.13

to BuddyPress menu in WP-admin

function add_menu_link(){



add_submenu_page( 'bp-general-settings', "YOUR MENU", "Your Title ",

'manage_options', 'your-plugin-slug', 'your_function');

}

add_action( 'admin_menu', 'add_menu_link', 20);

// NOTE the addition of a higher priority seems to solve the problems where

//  WPMU starts trying to tell you that you don't have access (url is admin.php/?c=1)

I can’t take credit for this – the solution was here
