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.

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).

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

No
