 NuVotifier is a Bukkit plugin whose purpose is to be notified (aka *votified*) when a vote is made on a Minecraft server top list for the server.  NuVotifier creates a *lightweight* server that waits for connections by Minecraft server lists and uses a simple protocol to get the required information.  NuVotifier is *secure*, and makes sure that all vote notifications are delivered by authentic top lists.
