Unfortunately it is not possible to add users as admins of a group at the moment. However, you can add other users as course contributors to your courses in the group.
To do so, visit your course, and click on Edit course in the top right corner. Select the Contributors tab at the top, and add people by entering their Memrise username. Don't forget to click Save!
This is useful to share the workload of creating a course with another set of hands.
Course contributors can:
✅ create levels
✅ add items/words to levels/databases
✅ edit items

Course contributors cannot:
❌ delete a course
