dni lection books to lern dni

a year ago i found a website on the net where you could lern the
language dni with the help of some (7) dni lection books. as far as i
remember the site was www.dni-resource.com. but its "closed" for a few
months now. i even searched on archive.org to find those old pages, but
they weren't there. maybe one of you remember the site and the lection
books, because they were really well written und someone did much work
on it. neither google nor other search sites could tell me where the
site is gone :/
so i hope you can help me finding them or maybe someone mirrored the old
sites.
