I just opened a fresh server with the newest experimental version, for those who would like to experience the new world generation together.
This is brand new, and a test server, no spawn, and no plugins, or features, just raw vanilla mc.
However, do know as this is an experimental version, after the regular snapshots come, some progress will be lost.
You'll have to use the 1.18 experimental version to join of course.
If you don't know how to install it, just type '1.18 experimental part 2 minecraft' in your google search bar and select the first or second result.
