http://www.youtube.com/playlist?list=PL1132B45B30FD92D3&feature=g-all-a Good production values and high-quality content it seems. I like how the visual material is concentrated on real game-like play. Worth watching through IMO.
There is also a written manual available at http://bwfbadminton.org/page.aspx?id=19994 You just need to fill out a short form and send it to BWF.
Got my coaches manual today and had a quick overview. First impression is really good. This level has its focus on the basics of badminton training/coaching and it goes hand in hand with those youtube vids. I'm impressed so far
Got mine too, and there is info that the level 2 will be released in June. Hope it will also be for free
