Is there a way to limit the number of times a workbook can be opened? The
idea is to update a spreadsheet (workbook) template every few months. I
would like to control the primary workbook and have the older workbooks
implode after using it 5 or 10 times.

Is there a way to restrict the spreadsheet from being forwarded as an
attachment?

One could include some VBA code to do this, but it's useless if the
workbook is opened with Security set to High (or with the Shift key
down).

No
