It's a PBEM, but ingeniously automated. It checks its own e-mail, updates the website and hosts at the right times, by itself. It's been my big project for quite a while.
There's no need to use a password, since you'll be the only one to ever see your turns. Probably better not to in fact (easier if anyone needs a sub).
It is mid-age, and for some reason I put late when I was creating the game - well spotted! Fixed now.
