How to post on 2 seperate "Pages" or "Cats"

I need to be able to make posts and not have them appear on the main page. How can I do this?

I'm using the main page as a blog that will have post daily.

I need to be able to post to the secondary page and not have it show up on the first page.

What is the best way to set this up? Do I need a PlugIn?

I tried Page2Cat but it just bullet point lists Category Titles.
