Depending on how your original letter (or template, whether it is really a
Word template or not, i.e., the name ends in *.dot instead of, e.g., *.doc)
there may be an even simpler way. Open your template, and look at the date.
If it shows today's date, then you probably told Word to "Update
Automatically" when you originally inserted the date. In Word 2000, there
is a box you can check in the Insert, Date & Time window to Update
Automatically. If so, that's your problem. To fix it, delete the old date
entry completely. Insert the date again, this time making sure that you
have unchecked the automatic updating. Then save the changes to your
template.
This will fix the problem of opening old letters and documents and finding
today's date on them. But now you will have another (small) problem: each
time you open the template to re-use it you will have to change the date. I
found it easier to leave the date out of my templates altogether because an
old date is another typo that can slip into the mail unnoticed and make you
look unprofessional. I found it better to replace the date in the template
with nice big capital letters reminding me to, uh, "insert the date,
stupid!" Now if I forget to insert the date, the mistake will be pretty
darned obvious when I proof read it. This method is 99% effective for me.
Since I'm the guy they call stupid, you may get better results.
If you are frequently re-using an old letter or other document as a form or
template to create others, you might want to consider using a Word template.
It might save you a bit of work and prevent accidentally wiping out your
"template." It's pretty easy.
