Undoing a move ==
Sometimes we move things and regret it later. Normally, to undo a move from page A to page B, simply:
move page B back to page A
# list page B (now a history-free [[wikipedia:redirect|redirect]]) on [[wikipedia:redirects for deletion|redirects for deletion]], or ([[Wikipedia:Administrators|admins]] only) just delete it.
However, if page A has subsequently been edited, or the move software is behaving weirdly, only an admin can sort things out:
# delete page A (make sure it has no useful history - you may wish to add an explicit author credit on a talk page to compensate)
move page B to page A.
# delete page B (should be a history-free redirect to page A)
"Move wars" are highly unproductive, and leave vast numbers of pointless redirects littering the place, which some poor soul will have to fix. [[Wikipedia:Staying cool when the editing gets hot|Keep cool]]: don't engage in move wars.
