To give thanks to the most dedicated members of the World of Warcraft community, Blizzard will be giving out prizes every week to groups of players based on how long they've been playing the game.
These giveaways will take place between now and the fast-approaching five year anniversary of the launch of World of Warcraft on November 23rd, with the first week's winners to receive a World of Warcraft Charge of the Great Dragonflights stein.
Contest rules and additional information can be found here.
