People are lazy, anything you can make that will simplify their lives is winner. This one feature certainly helped Social networks grow over traditionnal forums. Look kids, you can post stuff but you don't have to type anything, how cool is that? 😜
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.
