There are mainly two websites through which our members play go (although others exist too).
You should make an account with either of these to begin with, but you can log in as a guest. Games on KGS are played in real time, whereas Dragon Go is more like correspondence go where games can take a couple months or more.
If you want to play someone you know on either of these then you can find me, Kevin, on them. My username is jamble on both servers and I’m always happy to play new people or beginners. Just send me a message and I can set up a game.
