[Wikipedia-l] How idiot-proofed is the 'move' feature?

Move is not destructive; it will fail with an error message if the
destination page already exists or is an illegal title.  I also
just fixed one remaining bug in the way it updated the link tables,
so I don't see much reason to restrict it anymore.  It is, however,
still a fairly drastic move since it changes a lot of stuff at once 
and creates links to redirects, so it should probably still be
restricted to logged in users at least.

Can't do it--you have to move A to X, delete A, move B to A, delete 
B, move X to B, delete X.
