Swapping books

I just packed up my first book for GoodReads Bookswap, and it will be in the mail tomorrow morning.  This is really cool stuff. I put Saltwater Witch up as a book "I own" and am willing to send off to a reader.  Then a reader looking for books makes a request and GoodReads does the whole back and forth with addresses and even prints out the pre-paid shipping label on my side.  So, I signed the book, wrapped it up, and it's ready to go.

Anyone else using GoodReads Bookswap?
