Considering the current economic climate, I'm guessing more workplaces then ever are employing a secret santa policy when it comes to gift giving this year. If you got stuck organizing volunteered to do it for your office, you might want to make use of Elfster, a nifty website designed to help keep all the details straight (so you won't find out who is buying yor gift unless they tell you!)

Input the details of participants (along with any extra info such as gift exchange date and price limit) into Elfster.com and it will, assign gift-givers and email them all with the details. The only thing is can't do is take responsibility if you don't get what you wished for...
