I’d like to have a category where I restrict who can post new topics. Easy; just don’t give users the ability to Create within said category.
I want users to be able to hit reply and have Discourse default to creating a linked topic in another category.
I don’t think denying “Reply” on the category, nor simply Locking the topics will do what I want.
My use case is a category full of articles that are evergreen. I want users to be able to spin off creating topics for fresh discussion which are linked back to the original article (and of course they could quote in their linked topics.)
