- it is similar to the ELO-type ranking used on the ladder, and for chess, etc. BUT it allows games vs multiple opponents AND team games with teammates of different rating.

all players would have to have a rating, BUT if Fizzer set it so only members were told their rating, that might be a big plus in favour of buying membership, no?
