So winter4w hasn't specified the mods we can and cannot use. He says that we can't use any mods that give any advantage over another player. But that's kinda what mods are.... He says we can use optifine, which gives an advantage over others by giving better FPS. But just now he freaked on me for having a fullbright mod. It is not that big of an "advantage" It just helps me see better. Please specify all the mods we can, and cannot use.
