Created new page, need to preserve subnav links

site: www.parallaxgaming.com
new page: www.parallaxgaming.com/archives.php

I created an archive page (see above) for me to manually enter and keep track of posted news articles on our site by year. However, the subnav links do not match the homepage. I can make them match the forum root (e.g. new posts, private messages) by using the following code:

define('THIS_SCRIPT', 'index');

but I cannot make it keep the vB root subnav that you see on the homepage (not forums). What script do I need to define here to make it match the homepage? I tried vbcms (listed in content.php) but that did not work. I also tried a few others without much luck (news, home, etc).
