HI Stacy. But that is when you are using the British/Australian English language pack (en) rather than the US English language pack (en_us) Is there a reason why you prefer the English (en) one over the US English one?
Where does it say "show marks" in the US English version? As far as I am aware, if you use US English in your Moodle site then it should say points, not marks.
Yes, do please Rick. My understanding (I haven't tested it ) was that if there is no place for the Mark as done button to appear when a URL is opened, then the Mark as done button will always appear on the course page.
