I've moved this topic to the right section, sorry Neotron a bug occured and your post has been deleted during the move :s
Anyways this is a great idea and we have already think of it but it's really very difficult to set up and also find the best way of having ranking here (all games must be checked, players also... the game must be planed on the forum, players fix a date and record must be posted )
I thought a good way would be to make championships where everybody plays vs everybody (so the same number of matches for each player) and we count the point (the same system we have for football championships).
If you have other ideas, just let me know them^^
The best defence is attack!
