Bahaipedia:Subpages
A subpage is a page that is dependent or subordinate to another page, or that exists completely within the context of another page. Pages in article space should not have subpages; they are generally most useful in non-main namespaces.
For instance, a complex template or module may use subpages to implement sub-procedures used by the main template. Users often create subpages of their user page for use as personal sandboxes. Certain parts of the Bahaipedia namespace use subpages, especially ones related to WikiProjects or other major site features such as Today in History. Talk namespaces often use subpages for archiving past discussions.
Subpages can be created by appending the name of a subpage to that of an existing parent page, separated by a forward slash (/). For instance, the page User:Dragfyre/Dashboard is a subpage of the user page User:Dragfyre. At the top of any subpage, a link to the parent page will appear, allowing users to navigate easily through subpages without getting lost.
