Thats absolute rubbish, there will be people whom are log on a daily basis but don't post, either because there is no valid contribution to make to any of the current threads or because they don't have time to do that.
People have their lives outside of the world of forums, to go by your argument, then a person would have the right to CF privileged just for posting lol....or roflcoptor or some inane rubbish like that, so if so lets bring back people like windowsvista, and furby etc, and give them that.
I am not sure if it has been ever completely 100% clarified what it is awarded for, but in my opinion, it should go to those members whom make a positive contribution to the forum.
