I have delegated in-game administrative and SourceBans++ access to out Fistful of Frags (FoF) servers to the FoF-related "Saloon" community. They are a very active community playing, supporting and promoting the game.

The "Saloon" community is mostly active in Discord, but they do also have this Steam Community Group.
