Frosty Chests of Frostivus are scheduled to expire on January 3rd, 2013, so we should use this, the day before, to get as much Greeviling in as we can! There's no telling whether or not it will truly be the end of the game mode based on how long Diretide went on for, but it's a safe bet. If you want in on the Greeviling, keep your evening open, and we'll get it together when enough people show up.
