In my understanding,

to put a nav bar on the left, there are two methods mentioned by two persons in this thread

1st method mentioned by vboard.co.uk
modify the forumhome template to make a two table
one on the left of the nav bar and one on the right for the forum

2nd method mentioned by Ed Sullivan
edit header template and footer template

<table align="left" width=150>
should do it.

Or

(in the header)
<table width="100%">
<tr>
<td><!-- Nav Bar --></td>
<td>

(in the footer)
</td>
</tr>
</table>


Please correct me if I am wrong
