Congratulations on 1900+ chess.com rapid milestone; personally, I don't share the feeling that 1900 is "not enough", but of course I'm still working on my chess and 2000+ would be cool
I've not yet reached 2000+ rapid on chess.com, but I have at least reached 2000 before on some inflated site we shall leave un-named

I would like to share with you guys that I reached my goal of overcoming the 1900 elo in chess.com
Suddenly I feel that its not enough and that i should go for the 2000,becoming a national expert.
Just to share with you that doing the thing right in this platform pays off.
