Hi, As we know, in NodeBB there is concept like "One Topic" has multiple "Reply" (Posts). I wanted to implement functionality which provides facility for the user to make "Comments" on each reply. So the hierarchy will be : --> Topic --> Reply --> Comment 1 --> Comment 2 Most important is I wanted to do this using PLUGIN approach. So Is there any similar plug-in available which can help me? If I want to implement this then how should I start this? Any guidelines. Thanks!!
