ETC locations was a project I took up initially when joining the wiki; I can fill that in and check for gaps if there's any. I'm also very familiar with Secret Locations, having updated it a handful of times, so I can give that a quick scan also.
Is there anything in particular under Sets that needs doing? I've added one or two sets before, so it shouldn't be too hard to pick that back up. I remember it being annoying because the preview doesn't display the set box at the bottom of the page correctly until you actually make the edit.
Afterwards if I have any more time I'll look into the contracts page, seems easy enough.
I'm not interested in Adro's project. I both respect his work there as his own and disagree with its intentions. I feel a wiki should only ever give out facts and data, and not personal opinions/ratings of different builds and skills.
