Recently, some of us have figured out that some posters edit their posts time and time again, even after much of the discussion has ended. For that reason, one of the other experts told me to pass the word that we should always "quote" the person to whom we are responding, so that person's text will be what we are responding to and will show in our answer box. If he or she adds to or deletes from it after we have responded, the difference will be apparent.
