Hello Alexander,
Always talking "IF THIS KARMA SYSTEM COMES TO WORK".
It must be defined how many hours/days the host is delayed. The other players can't wait forever.
Example: the guy gets married and travels for a 2 week honeymoon, when he sends the turn 2 weeks later perhaps another player (who has sent his turn on time) lost his interest and stops sending trn.
I think the hosting delay must have been asked by a player who has enough karma.
