how to ignore certain posts from a specific forum on search.php /getnew

[jeffj]

can someone give me some guidance on what code to modify to ignore new posts in a certain forum id when someone click the "New Posts" link?

On of my forums contains news posts via an rss feed and none of my members want those posts cluttering up the "New Posts" results list.

I'd like to modify search.php/getnew to ignore all posts from a soecific forum id, how do I do this?

thanks in advance.
