Shouldn't this request be directed to Taptalk Inc? They seem to charge both the app user and the forum maintainer for "pro" features.
As this is an open source project, they're free to provide a NodeBB taptalk plugin and earn more money 😉
It would be pretty usueful to I, as an admin of my NodeBB Forum, be able to choose wich users I allow to create/delete Chat Rooms, and give the admin the power of choosing not only users, but groups and several users canned in a Chat Room.
This may seem like a nonsense, but it's actually pretty needed for enviroments like mine. I use NodeBB with Mattermost, and all the admins agreed in the disablement of the InForum Chat, but this is some kind of a trouble, beacuse when I need to speak to a user about a problem on his account, or something, and he is not loged into Mattermost, I have to use other means of contact with that user.
as a temporary solution, you could just use email
