I've done some preliminary work in creating some (unofficial) CC rankings...before I spend too much more time on this is there any general interest in this? Please vote.
If I go ahead I'll give some more details on how I envisage on how it will work. It will be experimental as most of the effort is in determining a fair method in ranking gold and free players in some vaguely comparable way. I expect that the ranking calculations will be an evolving work-in-progress - starting out simple and evolving into something more complex.
