By the way, one of the things we experimented with on LiveJournal Zendo is whether to keep it turn-based, which can be very slow (especially if you allow mondo), or to allow koans and rule guesses to be posted at any time. This puts more responsibility on the Master to be fair and not give an advantage to a player who happens to be active at the same time as the Master and can make many moves in a row. Or, it can be turned into less of a game and more of a cooperative puzzle. --dougorleans@xxxxxxxxx
