We have gone to great lengths to organize and streamline the page tree in our Confluence space and need to restrict it so that only two specific people can create new pages at the root level. I still want others to be able to create child pages of those root pages, but I don't want the core branches to change. I have restricted the Home page to View Only, but users can still create pages there using the Create and template buttons. How can I restrict my page tree to ensure that it stays organized correctly?
