I regularly send excel worksheets to a co-worker via e-mail and then she
sends it out to others within the company (sales force). There are occasions
when she will need to revise it and send it back to me. How do I protect my
comments so that they cannot be edited, or can I? I received a worksheet
back today that the comments I had entered were changed. These comments are
my back-up and I do not want them changed.

Can anybody help?
