Tom,

I've got a bushel basket  full of cards that have come in over the past 
few years that I need to deal with someday.    Just trying to survive 
and can't worry about this rinky-dink stuff.

I try and discourage QSL's unless somebody really needs the prefix, or 
county, or whatever.  I  told the bureau years ago to  not send me any 
cards and they dispose of them.

If a card has a printed label on it with all the necessary info,  you 
can scan and OCR it so you can print out  one to send back.  Cards 
filled in by hand are a royal pain and need sighted help.    No 
obligation at all to reply to  any card that didn't include  a SASE.

on a semi-related note:  For the 2007 WPX CW contest, I let N4PN 
operate as KW3A from his home in Macon Georgia.  He handled all the 
QSL's for that weekend (almost 2,000 QSO's).   He then sent me the cards 
he had replied to and I shoved them into a drawer.

Since I no longer take bureau cards,  some DX stations  are still trying 
to QSL KW3A  via N4PN.     Once or twice a year  Paul sends me a dozen 
or so cards that came his way.   They wind up in the same drawer.

73, Steve KW3A
