Need help with include

Hi
I made a new page from bozUNtu theme, gonna use phpbb forum with this theme.
Using this tutorial
http://www.phpbb.com/kb/article/add-a-new-...-page-to-phpbb/

The test forum is located here
http://www.almennt.com/wp/phpBB

And the new page is located here
http://www.almennt.com/wp/phpBB/aboutus.php

what i am trying to do, is adding in news script "Cutenews" with that theme using "include"
but i am not sure how i can include it to the about.php

aboutus.php

<?php
define('IN_PHPBB', true);
$phpbb_root_path = './';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);

// Start session management
$user->session_begin();
$auth->acl($user->data);
$user->setup();

page_header('About Us');

$template->set_filenames(array(
	'body' => 'aboutus_body.html',
));

page_footer();
?>

aboutus_body.html

<!-- INCLUDE overall_header.html -->
