How do I hide the names of players? I have a survival/pvp server that should hide them so it's harder to get killed.
The only way I can think of to do that would be writing a plugin that alters packets sent to clients to make all players appear to be sneaking. See if such a plugin exists on dev.bukkit.org/server-mods. If it doesn't, request it in the plugin requests forum. Also look into TagAPI - but I doubt that will do what you want
