I will say I misspoke when I said 'split' solely in regard to GM Kee, but there was definitely a split within MDK where some stayed TSD and some went TKD. It is easy to find with a Google search, but I believe the largest MDK TKD organization is the Pan-American Moo Duk Kwan Association (my how Koreans are all about names), with the Korean MDK Association a close second.interesting - the stuff I have read was that Hwang Kee never employed the TKD moniker, and some indications that he was really opposed to it. If you have any sources about his adoption of that moniker I would be interested to see it. Because of what I have read I always felt referring to MDK people as TKD people might be looked upon as an insult. Hwang Kee - Wikipedia
