I was looking for a book about playing badminton and found this thread: http://www.badmintoncentral.com/forums/showthread.php?t=7813

Too bad the 2 links to his books are dead. Is there anyone who knows where I can download these books or can someone mail them to me (fw.raptorman[-at-]gmail.com). Thanks in advance :)

Nevermind, found it.
Kwun, maybe you update the link :)
