I got this idea after Rusty sent me a book to read.
You know how we recommend books to each other, well what if we shared them instead of going out and buying them. We could post them to each other for a few pence instead of paying pounds for them from the shop, and then just post them back when we've read them.
We could put each book down as a new discussion and the if anyone would like to read them they could just leave a message under the book title. (but email each other the addresses). What do you think?
