Tracking Changes

[Ashish]

Hello,

I would like to know if there is a way to track changes in
Excel in the following scenario:

I work for a company that posts Excel sheets on the web on
our website. I need to make it so that any end user can
open up the document, make the changes they want, print it
out, and have the changes highlighted with no other steps
needed. So far, I need the person to activate track
changes after they make their changes and I want to get
rid of that step. Saving the sheet with "Track Changes"
activated does not seem to work because the end user still
needs to turn it on after making any changes or else
his/her changes are not highlighted when printed.

Any ideas?

Thanks,
Ashish
