It dawned on me while playing how nice it would be if I could send a challenge to someone after I finished a course.. Right now the way it sits, the message center hardly ever updates and really is broken.. So assuming that HBS knows that we would like better social integration, how about adding a quick and easy way after a round for me to challenge someone directly to beat my score? That way when they log on they can see my direct challenge and vice versa. I know in the message center there is little messages that says such and such beat your course record, but it would be cool to send out a challenge ... This would be useful with friends I would think... Just a thought..
