Hi, if the course creator is a member of this forum, then you can tag them so that they will see this post using the @ symbol and then the persons name like this- @fusil24. However this will only work if they are a member, as not all course creators have found their way here.
If the course creator is not a member of this forum then you could ask a member of staff to invite them here. If that fails, you could ask to be made a contributor for this course.
I’m afraid the course creator and -contributor are no longer active on Memrise. @lusa74, I have added you as a contributor. You should now see the ‘Edit Course’ button when accessing the course. Further instructions can be found here.
