I've stumbled on a couple of the other month boards and they are doing holiday card exchanges. I love getting mail and we only get like 3 Christmas cards-one is from our dentist. For some reason our family just doesn't send them out.
I know this is moot at this point anyway and some people aren't comfortable giving out addresses. But still could have been fun!
And by the way, some of these other month boards have a massive amount of people participating! One is even talking about doing a wedding gift "secret santa" type thing. It's amazing to see!
