I’m sorry about being off-topic (Am I?) but… Isn’t that, like, way too much for a forum, even a large one?
The more admins you have, the more the chances are that arguments with potential havoc can happen.
I fail to see how 20 people can envision the same goals and management on a single forum on which they have literally all the rights.
The only persons at an upper level are the ones who have access to the server’s root access.
I understand your concerns and issue Daniela, but from my perspective, maybe reducing the number of administrators (by making them moderators, trust level 4 or regular users) would be a good idea to limit the risk of this kind of problem.
I’m aware that my reasoning may be wrong.
