Gophernicus is a modern full-featured gopher server.
Gopher is a protocol that was for a brief shining moment more powerful and useful and usable than the World Wide Web. That didn’t last long, and what’s left of Gopher is refreshingly small and non-commercial.
To create a Gopher server directory on Yourtilde, follow the Gophernicus directions to put a ~/public_gopher directory in your home directory. Populate that with files or gophermaps or both to make your little corner of gopherspace.
