KingMe lets anyone in your party whisper you and take the crown. Written primarily for guildies and friends, this is a trust-based addon.
After installation anyone in your party can now whisper "!kingme" to you to take control of the party. There is a simple configuration section at the top of KingMe.lua. Cannot be used to take control of a raid.
