I'm a big fan of ShinSekai Yori, both the novel and the anime/manga. I'm truly glad you have adopted this wiki, but I was wondering if you're in need of an admin. I've seen people aren't as active on here anymore, and I thought I could help out.
I'm not looking for other admins as of now, since there is no need for it and I would only give such a position to someone I know and trust. You can edit as common user instead, as editing doesn't require any admin rights.
I'd also ask you to take a look at the wiki rules. I've seen you uploaded a lot of images under terrible file names, whereas the rules state that files should be kept under coherent names. It's impossible to find files under such names and renaming them takes a lot of unnecessary work.
