completely delete pages (remove them from RecentChanges, remove associated revision history)
rename both existing and unreified pages and all links to them, including those in RecentChanges
How do you do this? I've just set up a [wiki] of the same kind as this, and some of my users are already playing silly blighters. Can you just delete it out of the page and keep directories and have it vanish?
[action=editlinks] is your friend. You could just delete it out of the page and keep directories, but that won't remove it from the RecentChanges log; and action=editlinks also handles renaming pages sanely by going through the wiki database and renaming all the links to them. In general, look [here] for UseMod admin info. - MoonShadow
see MaintainMe for info on how to request that I do one of these, and also for a log.
