I'm around 12 kyu and haven't played for a few years.
My sole potentially useful contribution to the Go world so far: a Go variant intended as a teaching tool for noticing ko threats, playable on unmodified online servers. I think it's fun and useful! To be played only rarely, however, to open one's eyes to ko threats while not ingraining in oneself a potentially weird and wasteful play style.
