Support Forum Plugin
In a nutshell, this plugin allows a forum admin to configure one category as a "Support Forum". The category will then differ in one significant way: Topics created by regular users can only be seen and accessed by replied to by the topic creator
As normal, administrators have access to all topics created in the chosen forum. This allows a forum to become a private "support forum", where private information can be shared freely.
Install via NodeBB Admin Panel, or
npm install nodebb-plugin-support-forum
