+>> That's a blow; I was planning on appointing no techies to keep law and order on our pages :-/ Is there a plugin or at least a plan to add such a 'in demand' feature?

+Update: Web reversion is now supported by ikiwiki. Only changes committed
+to your wiki after you upgrade to the version of ikiwiki that supports it
+will get revert buttons on the RecentChanges page. If you want to force
+adding buttons for older changes, you can delete `recentchanges/*._change`
+from your srcdir, and rebuild the wiki. --[[Joey]]
