Due to an inconsistency between Moodle's forum and the automated emails it sends out, some of you saw the entire announcement above, while others only saw an earlier version that did not have the quiz reminder. Sorry for the confusion... Moodle does not always behave as we expect it to. We will therefore move to Thursday the quiz we had in mind for today, but it will still be on last week's material. There will be another quiz next week, on Tuesday as usual, covering this week's material.
