Anyone wishing to participate in redditgifts’ Secret Santa 2013 can sign up at http://redditgifts.com/secretsanta. Each user is asked to fill out a profile that includes likes, dislikes and any other information that might be helpful to his/her Secret Santa. Users must have or create a redditgifts account in order to participate.

Each registered user is matched with a gift recipient and a secret gift giver. Secret Santas are encouraged to check the profile information for their gift recipient in order to choose the perfect gift. Reddit recommends each Secret Santa spend around $20 for a gift, which must be shipped by Dec. 20.

Once a participant receives his/her gift, reddit invites them to take a picture and post it to the redditgifts gallery in order to share in the global merriment.
