thought ross would answered, but I think its if you have a book offer it up to loan out , post it to who wants it,and when it's read,say on here and you post it on to next person who wants it.
its a trust thing, hoping they dont get sold, stolen etc.
the 2 pighunters are mine, pm me your address and I will post you them,but it might be next week, as im busy, you can then say when you read them on here and see if someone wants them and post them on or back to me I dont mind..
I missed that post but yes that's more or less how it works.
