You need to know how news works
When calling the news page the view.php script is executed and gives you the headlines.
When clicking on the read more link the same view.php is executed, giving the details.
So basicly there is no easy way to make one script having 2 templates!
But we can do a lot with wb....

In order to make it look like 2 different templates you can easely do this:
make the news page with the template you need, the template you want when clicked read more... link
make another page, in it a code section and choose the template you need for the header list. Give it a code section and paste the code (
http://forum.websitebaker.org/index.php/topic,409.0.html) to show the headers.
This way the listing of x newsitems are done in one template with a bit of code and the actual newsitem is displayed using the template for the newspage.
Easy does it

Happy baking,
