Dag Gordon,
Hm you seem to remember me! I'm a rather vain person, so that is nice.
It's the corona pressure that brought me back here.
So, I started a new Moodle all by myself. https://hennyjellema.nl/moodle/ But a lot is changed, and I forgot many things. And I'm out of routine.
But I think my 'grades-problem' is solved by a very nice friend, who attended me at the function 'appearances' when starting a new course. There one has to give 'yes' to gradebook visible'.
But there is still a lot to dig up. Now I wonder how was it when we want to a chain of Potaoes in Moodle. Hadn't you made that? Quizport? Chainport? How do I get that in Moodle?
Maybe there is somewhere a manual or so?
Hartelijke groeten,
