ok, I figured it out. So, if anyone else is trying to do this, here’s my solution:
On page.php, I changed:
<?php get_sidebar();; ?>
to:
<?php if(!is_page(‘Forum’)) get_sidebar();; ?>
Then, there was a blank space (where the sidebar used to be). I created a div titled widecolumn with a width of 100%. Then, on page.php, I changed the original div (contentleft) to:
<?php if(!is_page(‘Forum’)) { ?>
<div id=”contentleft”>
<?php } else { ?>
<div id=”widecolumn”>
<?php } ?>
Yay!
