Hey all, I just published an android app for playing go against others over the internet, including matching based on rank and handicap using elo rating. You can play online at http://go.mut8ed.com, and the android app is at https://play.google.com/store/apps/details?id=com.mut8ed.go. I'm hoping to create a great community of players of all skill levels, so please check it out.
Link seems to be down.
Checked again. The google store link is working but the other web address is still broken. Looks like an abandoned project.
