It'll prolly take a month or more to prepare.
The plan is to put it together so it will
stay together after lots of unpredictable handling.
But hopefully not that long.
The idea of a blank book circulating, gradually being filled, is one way to do this.
Another is to have everyone who wants to participate, do up their own page(s), then send them to one location to be made into a book, then send around the completed volume.
Either way it is a really fun thing to do, and a shame that some have to feel paranoid about it.
