How to: Excel footer which tells me which user last saved sheet
 

Hello. At our organisation, we keep our monthly staff meeting minutes in a
workbook. Any member may take the minutes and type them onto the next sheet.
At the meeting it would be great if we knew who had typed the minutes. I
cannot find a way to add something like &[last saved by] in the footer of the
template. Could someone let me know how. Regards, Amanda
