Thanks. In the meantime I’ve learned that my inability to send a message was because I had just joined the community and sending PMs was disabled.
It has since been enabled and like you say, it seems Dave isn’t active as a member.
I had also found the procedure to become a contributor, but I have to wait a week before submitting a request. So Step 1 = check
By the looks of the leaderboard, there are other users actively using the course. I’m not sure how I can find who might be a contributor.
So let’s wait a week.
Thanks a lot for the feedback,
