I already included the definiton and link to The Merriam-Webster Dictionary dictionary which defines an arena as "a building for sports and other forms of entertainment that has a large central area surrounded by seats.arena definition" but an anonymous user just keeps reverting to a list that insists that the Philippine Arena is the largest indoor arenas by capacity and this is far from reality. How can we keep this from recurring?   10:28, 12 January 2015 (EST)
