nav bar problems

When I create a new page, It works fine and shows up in the nav bar however upon clicking on the page in the nav bar, it not only highlights the page's button, it highlights the home button. Does anyone know how to fix this?

Also, I am trying to make a page that users can go to to makes suggestions on how to make my product better. What type of page would be best for this. I would like to avoid using a link to a blog group if possible. I just want a simple area for people to make comments and maybe have others agree or comment on these comments. Any ideas?
