How do I edit this theme to remove the two sidebars on the right?

Hi getwithrobby,

If you want to remove the sidebars only from the contact page,
download “page.php” (located in wp-content/themes/amazing-grace/)
and remove <?php get_sidebar(); ?>.

And add a class name content-wide in <div id=”content”> so it will look like

<div id=”content” class=”content-wide”>.

Download style.css (same location as page.php) and add the code below.

#wrap .content-wide {
    width: 980px;
}
