So what do e.g., lawyers do--people who keep all their client files digitally? They can never know what dates other lawyers' letters were written. I'm assuming the law firm I used is not the only one that uses a date field. Should companies who have a date field in their template be doing something to their finished letter to keep the date from changing when the recipient opens it? Seems to me if you are keeping a letter, you are llikely to want to know at some point when it was written....
