hehe, I saw that 1 and laughed. Yeah, you had the file attributes idea correct. if the file works and 644, leave it alone. If not, reset it.
Code:
In NAVBAR: (link in navbar)
Find:
<if condition="$show['registerbutton']">
<td class="vbmenu_control"><a href="register.php$session[sessionurl_q]" rel="nofollow">$vbphrase[register]</a></td>
</if>
Add BELOW:
<td class="vbmenu_control"><a href="rules.php?$session[sessionurl]">$vbphrase[my_rules_phrase]</a></td>
Or you can load the template hook var in your php code and display it. That will require using a hook.
