In cooperation with WikiProject Outlines and WikiProject Indexes, make a comprehensive navigation system of Wikipedia that lists every page in the encyclopedia.
Note that outlines, indices, glossaries, timelines, and tables have their own standards. See their respective WikiProjects for details.
Note also that some "List of " pages are misnamed, and are actually outlines or indices, and fall within the scope of those two WikiProjects. Most of the misnamed lists include "topics" in their titles.
