Hi all,
as discussed during the GNUStep meeting, a Nicola's resources were partially missing.
I was able to retrieve from web archive the JIGS documentation and website. I needed some cleanup since WA injects JS code and alters all links, but I think it is fine now.
https://home.gnustep.org/jigs/index.html
Also Nicola's tutorials were apparently missing, yet most were present but the links were broken.
I kept the original page: https://home.gnustep.org/nicola/Tutorials/
But integrated them in the Documentation page where they are directly accessible.
https://home.gnustep.org/developers/documentation.html#minitutorials
Integration in the main website can be improved, but for now everything is salvaged and accessible.
