chan challenge notices

As a clan leader, i think it would be really useful if the message that the robot sends when one clan challenges another could include the names of the players the challenger has nominated to take part. even better, if would be great if there was a feature so that clan leaders could indicate they will accept even challenges only - say challenges where 50 per cent or fewer of the challengers have higher ratings than their opponents. there seems to be a propensity for stronger clans to challenge weaker ones, just to get points...
