Problem viewing only new topics

I have a website that uses pun as the message board. We have integrated the userdb, login, and more, but can't find a way to pull the same post results as we get with forum/search.php?action=show_new. Currently, what we do is on login, direct users to that page, and then there is a link back to the main site.

What I would like to do is pull the same posts with extern or similar so I can use it in my main site.

Any thoughts?
