My favourite spanking site is Bottom Lines .. it has a very lively forum and a whole host of other features including a Punishment Book, Norty Corner, gallery, library with over 1,000 spanking stories, chat room, games arcade and casino .. and it's all free. It's really for people who want to actively contribute to the forums though rather than lurkers. Anyway, the address is:
