Thanks for your reply.
Well, I am not sure. My horizontal menu at the top is my category list. So, it naturally seemed like the right thing to do for me to just add another category there and then add the fields I wanted.
My question is, how would I get a "page" to show up horizontally next to the categories if I were adding a page? A page seems to be the right way to go, but I want it naturally integrated in the navigation menu
