i posted about it at Toma's Room and i now have 17 people who want to be included. and 1 person from here, so that's 18.
i think i might be able to squeeze a few more people in, if you REALLY want to participate. but that's it. the little note paper i will write the msgs on is thin, but 18 will bulk up the envelope a little, and i don't want it too big.
