then you need some work, if you want to make 2 colums (one for the forum and the other for the navigation links).

You may try to wrap the hole table forum with div classes. Something like:

.wrapper {margin: 0 auto; width: 100%; border: 0px;}

then wrap the forum code inside. Something like this:

<div class="wrapper">Forum code here</div>
