There is no cost to join either of the exchanges.
To join the Christmas Card Exchange, click here
. That page will also tell you all about it. When you join your name and address will be added to a list. At a certain point early next month, you and others on the list will be given access to the list so that you can mail Christmas cards to each other. The only cost is what you incurr in cards and postage. Last year, the list was about 100 names.
To join the Ornament Exchange, click here
. That page will tell you all about how it works. Once you join, you will be matched with another person who has joined, whom you will contact and share information with. You will then either buy or make that person and ornament and ship it to them. The costs are whatever you spend on the ornament and shipping to that person.
If you go to the Front Office area you will see this thread
and this thread
about both exchanges and questions/answers folks have had about them. I update them from time to time with new names/additions. Time is running out on both these events, so act soon!
