Sorry, this is what happens when you try and use LiveJournal at midnight in the freezing cold. It's no small miracle my message didn't come out as:

"chllenge accpettd!"

My fingers are like jittery frozen sausages, and typing with gloves is tricky.

*ahem* Sorry.

Um, yes, I'll go and hunt down a copy of the book, and let you know what I think. I may also end up posting a similar challenge myself.
