if you want to set up a free account and play online via a "play by mail" type format. You just play through your browser, if you login and check in it'll show you if your opponents have moved and it's your turn. It has a nice "analyze" utility where you can take the current position and move the pieces around to check out various lines.

The site will rate your play and adjust up or downward based on your results.
