@LeuGim sorry to hear that, I'll try to fix it later today. I'm not a webdev, so I was under the impression that the `Access-Control...` part was to be done server-side.
As for the `innerText` bit, you are right, Firefox only added it in 45. I'll try using `textContent` instead, which should be good for IE9+. Other common suggestions seem to be: * some indicator that it's doing something * work in preview And maybe a button to go to `play.nim-lang.org`? (Sorry for going OT, if you have more suggestions consider raising an issue in nimforum repo)
