The staff are volunteers for the most part. The only people that get paid are the site/game devs. They however probably do not work at an office. The community is spread across the world. Really the only person with full power is hampa, the site owner. Other than that there is sort of a checks and balances type of system that stops one group from having all of the power.
That's not the building I went to when I was visiting 'em.
Unless I did something dumb, I've got a picture of their door somewhere. Presumably some pictures of the office too, but I know I took one of the door.
