With Excel 2002, you can allow format changes when you protect the sheet.
This would include all formatting (number, alignment, etc) except
protection, of course (wouldn't THAT have been embarrasing?! <g>).
I was stuck on the computer with the oldest version of Excel when I was
researching it. (I'm too embarassed to admit WHICH version I was using.)
This would be a good time to encouraging upgrading a few computers.
Thanks also for the suggestion about the use of color. The more I think
about it, the more I think that there are better was of doing this.
