this is assuming you have cloned your templates so that they can be edited. and, have added a static content page
if you need help on cloning your templates see this:
http://www.dcdezines.ca/articles-article.articleID-7.htm
to add static content create a php file myhtml.php or whatever:
<?php
include("mainfile.php");
include(XOOPS_ROOT_PATH."/header.php");
$xoopsOption['show_rblock'] = 0;
?>
add your html here
<?
include(XOOPS_ROOT_PATH.'/footer.php');
?>
