New nice list

Name the list and pick its rules. Then you invite the others from its page.

Who reads the letters?
When is the draw?

Everyone writes a letter to Santa. In the draw each person gets someone else's letter and buys that gift; nobody draws their own. Until the draw people can join and write letters; after it, nobody can join.

Once the list is set up, on its page you can pick pairs who do not draw each other, e.g. spouses.

What does the draw show?

With the name hidden there is a second day: the gift sack opens and the names show up.
