DoYouNeedThat provides an interface for managing potential loot upgrades dropped from dungeon/raid encounters. It allows you too easily see who recieved loot and lets you whisper the looter with the click of a button.
Usage
The loot window can be opened from the minimap icon or through the command /dynt
If you wish to configure the addon you can do this in the WoW interface options under the DoYouNeedThat tab.
