They're textbooks for students of Moo Duk Kwan Taekwondo, covering everything from dojang etiquette and tying the belt, to required poonsae through Moo Duk Kwan 3rd Dan and Kukkiwon 4th Dan. Working on another that covers one-step sparring and self-defense applications.
They're pricey, because there are something over 800 color pictures, and color printing is expensive.
Both are available through Blurb, and the second is available as an iBook. Just search for Moo Duk Kwan.
But they were never intended to be commercial. Our school isn't commercial, so why would the texts be?
The second book is available as a PDF. I give it to students on disk. If you want a copy, just contact me via private message with an email address and I'll send it along.
As for the dojo storming... My impression is that Nate is a kid (my guess would be just a few years older than your daughter) who spends too much time watching TV and has never learned to separate fact from fancy.
Sent from an old fashioned 300 baud acoustic modem by whistling into the handset. Really.
