Sub Into section - remove from other pages

I only want the Sub Intro section to show on the home page, and remove it from all other pages. it just takes up too much space, and it doesn't make sense to show the same message or HTML in every other pages.

I can't find where that code is located - can you show me where to edit, and what I need to do?

To be specific, I'm talking about the section that is controlled in the Admin->Homepage area titled:

Your Network sub intro post text
you can insert post text for the sub intro on homepage

Thanks!
