I got this idea for a snail mail chain letter from your snail mail list.
First person starts with big clean piece of paper and write a small paragraph of anything they want. They send to next person and next person adds another small paragraph to that same paper and send to third person, etc...
If you run of space, you start a new paper and send both pieces of paper to the next person, and the next person following will add on on same paper. After a certain number of people, someone could take a picture or scan of the papers for everyone to see what happened to the paper since they've last written on it.
Just a thought that was kinda interesting. Anyone interested?
