I was having difficulty managing/maintaining my time sheets for this summer (I was using a text file, one for each week, to document my hours). I was having trouble keeping track of the running totals and I noticed a mistake (probably due to duplicating a text file to edit it for the next week). So, this morning I spent some time converting the text files into a Google spreadsheet document that automatically tabulates the running totals. I will be adding Stewart, as a collaborator, to the spreadsheet when he returns from vacation.
