I'm on it daily. It isn't at the start of it's life but just recently became available for anyone to test. It has been in progress for quite a while and is probably getting close to full release.
If you see bugs or glitches you should report them. If you are on a full web browser you should see an icon that looks like a bug that can be used to provide a screenshot and details of the bug.
So I was just playing chess but then I saw the button on the bottom to check out the new Chess.com.... Very strange in this foreign and scary website. Too distracting and glitchy, which I hope will change as it is just at the start of its life. Any one else try it?
