This Weakaura helps guilds with an DKP / Auction System to assign their loot in a more "silent" standardized way.
As lootmaster (or guy with the item), whisper your self with the keyword "start" and the item.
The Weakaura now announce the item as Raid Warning and then starts a DBM Pizza Timer counting down for the time specified in the options.
After the time runs out, the auction is closed an a Raid Warning is posted to the Raid Channel.
