Uchronia: The Alternate History List

Does anyone know how to contribute to the list? I am aware of at least 3 works that fit the criteria, but I could not find any contact/"how to contribute" info on the website.

Too bad TLS is broken on this website. Also, On The Beach by Nevil Shute and Cryptonomicon by Neil Stephenson are missing (the former kind of appropriate again these days). The Man In The High Castle was there though. I like the idea, it can help gather people with a similar interest, but I think things like these also work well on a website where you can archive your book collection (ideally I'd want it offline, synced with an online DB) like Goodreads. Although ideally, not Goodreads, as its owned by Amazon, and the DB isn't yours.
