As your site grows, at some point you're likely to want to change the order in which the pages are displayed in the navigation.
The Navigation is that light blue section on the left with the links to your site's pages.
You might want to update the wording used in the links.
Or even need to make some pages sub-pages of another page, e.g. You have a page called My Photos, and you want to have categories or galleries of photos within that area of the site.
We have in fact added instructions for performing these 3 operations as sub-pages of the "Updating the Navigation" page.
