I searched through this forum but only found older threads. I also have a Demo site up, but I cannot find the option or don't know where to look.
I want to create a Node and Forum for Customer Support. To reduce trolling or wrong information, I would like to set this forum such that only the OP can reply to their own thread, as well as a specific group of users (Community Support Staff), and of course Mod/Admin.
Is this possible? Is it an add-on? Thanks!
