Exactly what code did you put into your site that worked (please use the code tags next time)? You are going to have to correct the html there since it looks like it is using <td> but there are no <table> tags around the whole thing. So, the first thing you need to do is put it all into the correct html structure -
HTML Tables
Once you have it in the correct table structure, then try putting it in your FORUMHOME template after the navbar:
HTML Code:
{vb:raw navbar}
PUT YOUR PROPER HTML HERE.
<div id="pagetitle">
<h1>{vb:raw vboptions.bbtitle}</h1>
<p id="welcomemessage" class="description">{vb:rawphrase welcome_to_the_x, {vb:raw vboptions.bbtitle}}</p>
</div>
