Do you remember the old Sombra ARG? Well, I just rebuilt graphically the old LumériCo website with all its old emails.
https://lumerico.altervista.org/en/
for those who don’t remember or don’t know this story I have dedicated two articles on a blog here: https://lumerico.altervista.org/en/what-is-this-website/
I hope it will be a good memory 
, with the only difference that I have translated the whole site into English and Italian (my mother language). Special thanks to the GamesDetectives community for their solved puzzles and e-mail collection.
