This may seem a very strange question but is something I have been thinking
about for a while. This is the situation:

I work in an office as the only typist for several people. At the top of
letters is a reference made up of the initials, in upper case, of the person
who has dictated (or handwritten) the letter followed by an oblique stroke
and my initials (in lower case letters).

So far, so good. However, if I am absent for any reason, the people type
their own letters by using a previous document and Save As..., or even type
a letter from scratch. They always use the same reference at the top of the
letter (i.e. including my initials).

Apart from an element of pride (I confess!) as they aren't very accurate
typists, this can lead to confusion when at some future date, they query
something which I have supposedly typed.

What I would love to do is to find some way of unobtrusively indicating in a
document when I have actually typed it. I have thought of entering somethng
in the document properties but that wouldn't work when they use Save As...

Any ideas, please?
