Removing Older Posts with Frontier Theme

Hi Ron,

I am using the latest version of Frontier. I would like to remove all posts other than those shown on the front page. I want only one front page. I would however, like to keep the older posts in the archives if possible. Is it possible to do either of these.
This is a fabulous Theme, but I don’t care for multiple pages of posts and slideshow. I also think these extra front pages may be slowing my site down.
