They were given 20 minutes of instruction / demonstration on a projector in
a classroom, as well as provided with written instructions.  I am certainly
open to - and always attempting to - improve my instruction.  But I feel
the instruction at this event was pretty good. In any event, having to
explain, "the 's' key will only work if you are reasonably close and there
is no error message" is just one more thing to explain and for the new
mappers to remember.

These are not the exact buildings as those were fixed during the mapathon
(sorry for the confusion), but at this mapathon I did walk over to more
than one mapper and watch them square a building with the 's' key, have
nothing happen, and then move on.  Most of the buildings they had drawn
were not square.  I pointed out the error and they did fix their buildings.
There should at least be an error message, something like "Failed to square
building, please redraw with angles 90 +/- 12 degrees"

JOSM will make the change, it may not match the imagery, but it will be
obvious that something has changed, hopefully prompting the user to make
adjustments and try again.
