i ran across a user on ebay (game-case-world) selling what looked like cover project covers. i messaged him about it and he sent me to his website, gamecaseworld.com
looks like he and his wife do some original covers, but there's definitely plenty of covers from users here.
anyway, don't know the full story and a search on the forum didn't turn up anything. maybe you guys are aware and gave him permission, but thought i'd bring it up.
