John,
Put on your mailin' shoes!!!!! Get the extra toner out for your copier!!!
Get a few sheets of "32 centers" from the ole P.O.!!
I offered a xerox copy of maggey 11-E in action a while back and was
cleanin' that up for a month!
Good luck John and thanks for the kind offer.
I hope those who accept this offer will send John a self-addressed stamped
envelope to help keep him solvent!
