[SOLVED] Is it necessary to use Pages or would Categories suffice?

Hi there, working on my very first blog, self-teaching as best I can

Initially, "Home" and "About" were my only Pages, and my Disclosure Policy page is under the About page. Please reference my site.

I would like to have just one menu, below my header image. Therefore I removed %pages from the Configure Header Area. Now of course my Disclosure Policy disappeared, because it is a page and I turned off pages. If I change my Disclosure Policy to a Post instead of a Page, then I could have it show up in the "About" category, in my category menu below the header.

However is there a reason I wouldn't want my disclosure policy to be a post? Does it need to be a page?

Dumb it down for me folks LOL!

Thanks.
