I use 'play by message board'. My favorite site by far for this kind of thing is called Rondak's Portal (
www.rondaksportal.com). It has tons of games available to apply for. Once you are in a game, you post messages on your game's own private message board instead of sending emails to everyone. Some DM's are better than others (I've had 2 just up and disappear one day, leaving the rest of us sitting there with a stalled game), but if you keep trying you'll find a good one.
