XF 1.2 Customize menu bar


How do I customize the top menu bar?
I would like a page where I can list the forum rules or FAQ and such on the menu so it is easily accessible to members. Much like the Resources menu tab above but single item.
Maybe I've played with Wiki too many years..

OK I hope this is simple -- going on the idea of navigation:

How do I simply made a page that is not visible, not a child of {root node}, etc.. until I access it via an link put elsewhere on the site?

I tried creating a Node of type Page, but the tool wants me to pick a parent. There is none.

Likewise, once I have fashioned this page, what's the URL syntax for it in the Menu hack above?
