In namespaces where subpages are supported , you can create a subpage simply by linking to the name of the subpage , prefixed with a slash ( e.g. \/ Archive ) . For Wikipedia , the User , Talk , and Wikipedia namespaces have subpages turned on ; the main ( article ) namespace does not have this feature turned on , as strictly hierarchical organization of articles is discouraged , and other distinctions are better made by placing pages in other namespaces ( e.g. discussions go in `` Talk : '' , and templates in `` Template : '' ) .
But their talk spaces and all other namespaces have the subpage feature .
