Click on the title to get pages about reworking/refactoring wiki pages.
Some WantedPages: MergePages, RenamePage (currently just has the technical aspects), CopyPage (primarily technical), RemoveRetractedText, RemoveRepetition, change TemporalOrder to LogicalOrder
See Wiki:RefactoringWikiPages, MetaWiki:refactor.
As a matter of style, we should probably standardise on "reworking", since "refactoring" is (A) about programming (B) jargon (C) has a technical meaning that isn't true for reworking wiki pages. (See WhatIsReworking).
Actually, reworking is about physical labour. "Rewriting" is the long-established term: RewritingText instead of the ugly WhatIsReworking. Or maybe "rewording".
