The Online Study Group (formerly Shodan Challenge) will be starting on 29th November and running for six weeks. Players of any strength who wish to improve their go-playing abilities are very welcome!
You are encouraged to choose a goal to work towards for six weeks, and a study plan to follow during that time. Using the group, you can arrange matches with players of similar strengths, request / offer teaching games, or discuss variations of a game you have played or watched. There will be a league system in place to help you find opponents of around your strength.
(Stronger players are also encouraged to join to help review games and offer advice. Please note that you are only committing to six weeks at a time, and you are not assigned individual students to mentor, so the level of commitment required is low!)
To sign up, please send an email  to me with your name and approximate rank (if applicable). Also feel free to send me an email if you have any questions, comments or feedback.
