Revision Tracking by row

[pslively]

I have a shared spreadsheet that multiple people will be updating. There are several rows of data, and a column for people to update if they've changed something in the row. People haven't been keeping up with that and I was wondering if there is a way to update the date and userid columns when a row has been changed. I have track changes on, but it's cumbersome doing it that way.

Thanks.
