I see into IA Upload queue some "probably failed" not-Italian items, but I can't get the email/the user name of uploader. Probably a it.source script could successfully merge OCR into djvu in items where IA Upload built a image-only djvu, but fails to merge text into the file. I'd like to try, but I need a personal contact  from interested users, just to coordinate upload of fixed djvu files into Commons.
