which runs the month of October.
Here's last year's thread: http://www.bookcrossing.com/---/523584
for the list of words/pictures allowed.
All releases (wild, controlled, OBCZ) count. As do multiple challenges--there are many words that are also allowed for the Tick Tock Challenge, so you can double up.
I ask that you post both the link and the title (and author if that's what makes the book count). Looking at a BCID number is no fun at all. Looking at the BCID *and* the title of what book you released is what makes it interesting.
No prizes--just for fun. Questions? Post here.
ETA: You can release all through October, or save them for the trick or treaters, or both.
