Your figures support what FromHell said. Inactive means are no longer playing, possibly have not even logged onto the site for years. Why would an unrated player be interested in discussing a game he don’t play?
Look at the chess board more closely, there is very little general chat. There was a big debate a while back over a technical point on ice age chess but other than that very little general chat.
As currently number 14 on the established grades in Chinese Chess I have no illusions that my standard of play is poor (and before you ask I have no desire to improve) and I would suggest there are no more than 5-6 strong chinese chess players on the site. I currently have either established or provisional rankings in 37 games on the site, do you expect me to engage in discussions on all of them? If not why should I treat Chinese Chess differently?
If an interesting point came up, an interpretation of the rules for example, I would be interested but posts about how your games are getting on are of little interest to anyone but yourself.
If you seriously want a discussion about Chinese Chess I would suggest this is the wrong site, you need to find one that specialises in the game.
