The guild runs strict loot rules when raiding. The rules are simple, and are as follows:
To clarify a grey area; bind on equip items (usually dropped by trash) count as "Your loot", and it is OK to sell these on the Auction House. It is good manners to offer this to the guild for a fair (AH) price.
Before raiding you will need to install the correct add-ons to be able to roll on loot.
