Vanish is a plugin for Sponge-powered servers, to hide some folks from some other folks while playing.
This plugin is the spiritual successor to VanishNoPacket, my beloved Bukkit plugin. The goal of Vanish is not to simply let you hide from others, but to greatly increase flexibility of player visibility on your server to suit your needs.
