Some names and naming conventions are wired into wiki client and server side code. We would like to discourage further pollution of this namespace.
Welcome Visitors is the assumed root of a site's hypertext. Pages need not be accessible by links from here but that would be an exception to convention.
Recent Changes reports recently changed pages. This is a feature of the Sinatra server only. See About Activity Plugin for the more universal service.
Recent Submissions is wired into the Submit Changes from local storage feature. See About Changes Plugin.
Search Results are pages created as client-side only ghost pages. Some paths lead to queries for this page on the server which appears awkward but harmless.
Exception: at one time dragging items within a search results page seems to write corrupted search-results pages to the server obliterating any proper page by that name.
Name Fragments
About Some Plugin would be the expected root of documentation pages for some plugin. Additional documentation pages should be titled with most of these words as in More About Some Plugin or About Some Plugin Configuration.
Some Template would be offered as a starting point when creating a page that has been found missing. The origin sitemap is searched for all page slugs suffixed with the word template. This depends on there being a sitemap and that it's loading has completed.
Some Sites would be a list of sites on some subject expressed as references to specific pages where the intent of the sites page is often to load the neighborhood with the referenced sites.
