P.S., IMO the first-aid icon in the lower right corner of the compose window is confusing. I just clicked it and I still think it does something else.
By "dynamic" I mean any environment where these kinds of privileges may be changing frequently. It's not just about moderation, it's about their roles in general (reading and posting privileges). And I understand what an administrator is, but that's not a clean separation. Admin and moderator are roles (not specific, granular privileges) and in one case represented as a group and in another represented as a privilege.
It's not that NodeBB doesn't suit my use case. After finding the moderator option, I can pretty much do what I want to do. It's about the spaghetti process it took to get there. I'd just like to see this be simplified and presented in a more coherent manner.
