No problem, and we might still hear from Mirko. Your post kept me sharp. I had to go back and review the grade book! Then I realized, "been there, done that."
It seems to me that this request has been around for a long time. Other LMSs seem to have this feature. I don't understand, from a programming point of view, why this would be hard to implement. All that is needed is another condition "Make empty grades be zero after due date," and a little bit of code, "if blank and today_date is greater than due_date, make zero." But as a non-php programmer, things always seem easier than they are.
