In your navbar template find the section that starts with:

<!-- nav buttons bar -->

Under that you will see lines like:

<td class="vbmenu_control"><a href="faq.php$session[sessionurl_q]" accesskey="5">$vbphrase[faq]</a></td>

Adding another one of those will add a new link to the navbar - just edit the href tag to whatever and replace the vbphrase[faq] with whatever text you want to display.
