You can add categories to pages, which is fairly simple. To do this, simply add the following to the end of your functions.php file:
[php]
add_action( 'init' , 'wps_add_cats_to_page' );
function wps_add_cats_to_page() {
register_taxonomy_for_object_type('post_tag', 'page');
register_taxonomy_for_object_type('category', 'page');
}
[/php]
