Yes, I know many (David and Geoff:-)) are probably calling me Pollyanna
right about now and it is true that most companies won't return it
if they think they can sell it. But I think having a procedure in
place to at least begin reclaiming addresses from those organizations
that are no longer in business can only help matters.
I personally oversaw the return of four /16's recently, so I, at least,
do not consider this to be Pollyannaism.
