This initial addon, AngryAssignments, was written by the guild Angry (US-Illidan) to handle assignments during raids. It provides a convenient way to store and share assignments for different bosses, allows editing by multiple people, and is able to display the information to raiders in a configurable format.
AngryEra is a fork of AngryAssignments focused on Classic Era/Hardcore/SoM with improvements for integration with Raid-Helper
