AlsoKnownAs is a plugin which lets you look up other names people have gone by. At the moment this plugin is completly useless as people can't change their name (Actual Minecraft name, not a plugin given name.) When Mojang adds the ability to change your minecraft name you will be able to use the /aka command to look up other names the player has used on your server. This plugin ties their UUID to a list of names they have used.
NOTE: The UUID of a player is different depending on if your server is on offline mode or not.
Looks up alternate names of a player Usage: /aka <player>
