Hey guys, while I was looking around, I found this very interesting Ever17 fansite (the downside is that it's in Japanese, but meh.)
http://blueforest.fc2web.com/gamecom...r17/index.html
It's got a load of fanart as well as a large amount of Ever17 fanfics (all in Japanese, unfortunately, but some of them look interesting.) It's also got some info on the game, though not as much as kgptzac's site, plus it's all in Japanese. So either way, while we may not be able to understand all of it, it's still a pretty good site.
