Not exactly sure what you are asking but you can connect to the site via web or via mobile app. That is pretty much it. At one point there was some discussions on a potential API but I don't know if the new site version is going to have anything like that or not.
Hi,
I was wondering if my ranking is something that would be honored if I were to connect to an ICS system? Does chess.com offer an ICS server to connect to?
Thanks!
