To quote from a newspost I got today from the official Yeonwoo OGS Group:
(…) the new school of Yeonwoo and Young Sun Yong, awesome baduk [at awesomebaduk.com is in beta testing.]
At the moment the school is still in progress, but I can tell you that the quality of the videos are amazing.
Imagine having the chance to learn from Yeonwoo like you do on the videos she posts, but also having the chance to ask questions about the lessons!
And on top of that, also learning from a World Champion like Young Sun Yong!
tl;dr Yeonwoo’s Go school project now has a webste at awesomebaduk.com.
