I'm looking for something that would let me store the board setup and move the pieces manually so that I can play with a friend via email/msn. It doesn't have to handle mailing or anything for me as long as I can move the pieces around :)
All you need is an e-mail address to create a small profile, same thing for your opponent, and you're ready to play. You should get e-mail reminders when it is your turn.
I haven't tried chess there yet, but if it's anything like A&A was, you should be in good shape.
There are many options for online chess.
A very simple site I use is itsyourturn.com.
You get email reminders and it just does what you need if you want play chess with a friend.
For more advanced options look at freechess.org. There are several different clients for it.
