My use case is this:
Participants in a paid for course get access to a restricted category to network with each other, and I want them to be able to upload files within our normal constraints as part of that.
Also associated with the course are some official files - they need to be kept distinct, and we can’t have a situation where a user might inadvertently upload something that gets mistaken as official.
My sense is this is a main category for the course and a sub-category with different permissions for the official bit - or is there a way of doing this in one category?
Or another approach?
