Squidward Tentacles was a member of the club, but not willingly or actively participant in it. He is also (not willingly) the president of the club. SpongeBob and Patrick caused Squidward to become a member and because of them he now has to do community service every Sunday for the rest of his life.
SpongeBob SquarePants founded it and was the only person present at the meeting that was awake. He also participated in stopping Squidward's house from destroying Bikini Bottom. He currently does community service.
