There are several different Administrators within the Nations Community. This page will help you to differentiate between the roles in the community.
The Game Creator is the person who, well, created the game, and also updates the game. That person is Stian Bakkane. He does not have a nation, and hasn't done any updates for a while, but is still the Game Creator.
The Game Moderators go round in the game enforcing the rules of the Terms of Services and making sure everyone is following the rules.
The Discord Moderators are people who are moderators on the Unofficial Discord (to join the Unofficial Discord, go to Useful Information). They enforce the rules of the server and, umm, yeah, that's basically it.
The Wiki Admin(s) go round enforcing the rules of the Wiki and creating pages that people are probably never going to read (like this one).
The current Wiki Admin is User:Isaacdnz (New Deutschland).
