I see two posts and one page entry. One of the posts is a copy of the page. You are right, I don't see the page entry being linked anywhere.
I checked the theme you are using and it holds the page links in the Widgets area. I added a Page widget and now it shows up. It's at the bottom of the sidebar. If you want it moved further up on the page, you can go into your admin panel, go to Design... Widgets.. then drag the page widget up and save the changes.
Hope that helps
