A kind of {shareware} that borders on {freeware}, in that the author
requests only that satisfied users send a postcard of their home town
or something. (This practice, silly as it might seem, serves to
remind users that they are otherwise getting something for nothing,
and may also be psychologically related to real estate `sales' in
which $1 changes hands just to keep the transaction from being a
gift.)
