The http://www.javascripture.com/Window#onbeforeunload event should take a BeforeUnloadEvent in the listener:

I was meaning to speak on changing that little saying since you have WHATWG's links also.

Maybe: JavaScriputer, the bridge between W3C, WHATWG, and ECMAScript.

I feel letting them know this will make it seem more friendly and feel a sense of choices if they dread reading w3c specs.

I don't have this on my local computer, this is all via Github. The help section suspect that I have prior knowledge on certain things.
