As I think I've said before, you don't do tech support, do you?  This may be
obvious to engineers, but Person A is going to be VERY unhappy because,
without warning, his changes were thrown away.  That all-important phone
number (this is a free-form address book function) is gone.  It's not good
enough to say in the manual that file sharing has problems, they won't
understand and will be calling about the bugs in the program (worse yet,
telling their friends how buggy the program is).
