To add a new page in BigTree, login at www.kenyon.edu/admin, open a new browser tab, and navigate to the page that will be the "parent" for the new page. Once you are on the parent page click the Edit in BigTree button.
In this case, I want to create a sample page that lives under the the BigTree Guide page. I can see Bigtree Guide to tell me I am in the right part of the site, so I can hit the Add a Subpage button.
The navigation title displays in the side navigation. The page title displays in the browser tab.
