You may encounter a situation where your pages aren't showing up in the context menu even though menu="true". The reason is because there are some words that are not allowed, the most common one brought up is "About".
Here is the complete list of what is not allowed. If you make turn a page node on for the menu and it has one of these titles, it won't show up.
