title: Auto-fill the date in a cell, when the user enters information in an adjacent cell
body: <p>I have a spread sheet, where people can enter project updates and then the date of the update. What is happening is that people are forgetting to date their notes. Is there a way to have the date cell autopoplute the current/date of entry?</p>
  
  <p>I am assuming an if function would do it? </p>
