Before sending the journal, the person in possession of it should e-mail or AIM the next person in line, letting them know that they're sending it, and for confirmation of home address. Since I doubt people would want to post their address on LJ, friends only post or not. After getting address confirmation, they would then send it, lather, rinse, repeat.
I'd like for everyone to reply to this post with a valid (and fairly regularly checked) e-mail address. Just in case we can't contact you on AIM for whatever reason.
ETA: This is me being intelligent and JUST noticing that this was posted in my PERSONAL journal instead of here. In May. STFU. Let us now ignore the fact that this entire project needs to be reassessed.
