"enough determination" == 4 clicks and type a new address (give or take a 
click or two - it's been a while since I did it - but it's not hard, and 
there are plenty of legitimate reasons for doing it, so it'snot hard to 
find out how to).
(This only works on some NC cards, but a few years ago it was over 80% - 
don't know current numbers).
