go to the navbar template:
find:
<!-- nav buttons bar -->
<div align="center">
<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="0" border="0" width="100%" align="center" style="border-top-width:0px">
<tr align="center">
below that code is the links you want. to add a link simple put this in:
Hardcoded style:
<td class="vbmenu_control"><a href="link_here">Text Here</a></td>
using phrase system:
<td class="vbmenu_control"><a href="link_here">$vbphrase[link]</a></td>
Where you just add a word (in this case "link") as a phrase.
