Search.php 'New Posts' - how to show only posts made by reg. members?
 

I need to somehow amend search.php, so when I click on "New Posts" at the top of the forum, it will show only those posts made by registered users/members.

So, when you click on "New Posts" link on my forum:
http://www.goldenretrieverforum.com/....php?do=getnew
it will only show posts from my members, not those posts I gather from integrated newsgroup system.

How do I change it? Is there any way to make this condition:
- Show post if it came from reg. member, otherwise exclude it from the list.

Can someone help?
