apostate -- Ah, okay. Yeah, you can just designate the "Why I Left Islam" page as having no parent. Then it will just be another bullet under "About" (your pages widget). However, you're left with a very large navigation tab above your header image, and then another will appear with the "Why I left Islam" title.
An alternative could be:
You could change the title of that widget (your pages widget) to something like "Basics." Then write a page titled "About." On that page you could just say something like, "Below are links to some essays providing essential background information." Then you have links to the "Who is the Apostate..." page and the "Why I left Islam" page. And you make *those* pages "children" of the about page. Ya know? Also, that will give yo a much smaller navigation tab on top of your header image, making room for others if you want them.
I have my blog set up something of like that, but without the links on the about page. (Cutline theme which works a lot like Pressrow)
