MediaWiki end-user notes of note:
- Go to Special:RecentChanges. Set it to Main namespace. Patrol changes to this site.
- Namespaces: Do an empty search. Click Advanced. See (Main) User ArchWiki File MediaWiki Template Help Category. The default namespace is in ( parenthesis ), otherwise navigate to a page by entering namespace:pagename in the search box. However... Sandbox is a "cross namespace redirect" to ArchWiki:Sandbox.
- Redirects: make it very likely anyone can type anything they want into the search box, And IT Just Works to go to a wanted page.
- Subpage links offer syntax, e.g. [[../../sister]] for both linking to and expanding page names.
- For searching, MediaWiki does offer a well developed package that surpasses all other search engines for this job.
