Add a player rating feature?

[ihack4fun]

I've heard a lot about players being verbally abused and opponents only going every 3 days (I've suffered from both), what if a player rating feature was added? Such that after the game you can rate your opponent and leave a comment about their attitude. Then there could be a way to look at and punish players who are vulgar or intentionally delay games for weeks. A safety on the system so these players also don't just give everyone 1 star would be a review of players who always give low ratings. What do people think? (I know this would be a lot of work for programming and such but lets just see if people like the concept. Also possibly elect admins who have played a lot to run it to decrease work load)
