On the subject of fan societies, i think it can be fun to be involved in a group of passionate people - and it can be fun to be a bit whacky - but it can also become rather silly and/or scary *this coming from a Potterhead who has walked through a shopping centre dressed in wizard robes.. oh, the shame!* Anyhoos, I think the book looks like an intertesting and enjoyable read. I recall seeing a Jane Austen Dating Handbook somewhere.. it looked most amusing!
Imagination is more important than knowledge... so's chocolate! and pillows!
