Assuming, of course, that you are a well-known member of the community with a level head and a history of contribution to the game’s fanbase. If you don’t even play the game, it might be more of a general “you.”
The position of Elder Guardian is strictly a volunteer position, but you do get a special title and the chance to relay communication to and from the development team. It’s sort of like a volunteer group of community managers, in other words. If that sounds like something you’d enjoy doing, feel free to throw your hat into the ring.
