We often use forum sections on other forum platforms I use as a way for members to privately contact staff - where Topics in those sections are only viewable by the Topic Starter and the Mod group.
Would be nice to add this to categories as well as specific tags on Discourse - where only Topic starter and Group members can view/reply.
What we’re looking for is something for Topic permissions. For example, someone posts a Topic which contains inadequate info - we want to move it to a Moderation Queue section/category where only the Topic starter and Mod team can see it
