It would be hard to make that tutorial much simpler. For the specific case of the reviews sidebox, copy and edit
/includes/modules/sideboxes/YOUR_TEMPLATE_NAME/reviews.php.
PHP Code:
/*...
* @version $Id: reviews.php 2718 2005-12-28 06:42:39Z drbyte $
*/
// test if box should display (added 20081221 -v)
if ($this_is_home_page) {
$show_reviews = false;
} else {
$show_reviews = true;
}
if ($show_reviews == true) { //(added 20081221 -^)
// if review must be approved or disabled do not show review
$review_status = " and r.status = 1 ";
//...
// MAIN PROCESSING BLOCK
//...
$title = BOX_HEADING_REVIEWS;
$title_link = FILENAME_REVIEWS;
require($template->get_template_dir($column_box_default, DIR_WS_TEMPLATE, $current_page_base,'common') . '/' . $column_box_default);
} //(added 20081221)
?>
