John August is such a generous guy. And I'm not saying that just to butter him up so he'll read my script. He really is a generous guy. If you've checked out his site (and I highly recommend you do), you've gotten a taste of the vast amount of valuable screenwriting information there.
Now, John's decided to dig his pool of knowledge deeper still. He's just launched jaWiki, a Wikipedia-like compendium of wisdom for the aspiring screenwriter. Like the standard wiki model, it's a place where we can all contribute whatever we can.
He does warn that jaWiki is a bit unstable and could self-destruct at any moment. But, hey...we're not scared. We're tech-savvy scribes, right?
