I just fundamentally misunderstood the project. I agree it would be a cool thing to try if it were based on the setting though, especially because I think you could get quite a few players who would be interested in contributing. Even if it's just for fun and not intended for publishing/profit of any kind. Plus, even if it were independently published by you to be sold, I'm sure most players interested in contributing (myself included) would have no problem waiving and percentage/earnings, instead allowing that to go to the publisher (you) and the site (Wes). This also re-instates my earlier comment that, if works were put together based on the setting, they could be injected into the setting as actual IC works as well.
But it would still be fun even if it's just about anything.
