So, I have started a new baguazhang (and xingyiquan) discussion board over here: http://baguazhang.proboards.com/
There are both English and Japanese sections; perhaps in the future I will add a Chinese section, but my Chinese is not really up to par (not sure if I can manage that). At present, the only members are me, myself, and I, so please go ahead and join! Feel free to be the first poster (there are some events listed, however).
The name of the board is Orthodox Baguazhang Research Society (正宗八卦掌研究社), and I hope it can serve to unite the various branches of orthodox baguazhang so that we can research together. (Orthodox, meaning verifiable lineages from Dong Haichuan - no home-grown bagua, please!)
