Openmine was a temporary world that I created a while back, I was going to delete it, but people asked me to keep it. I've decided to do so, with a big change: I've reset the world and switched it to V7 mapgen and the Ethereal biomes.
I've moved the old Openmine city to the new world in its entirety. If you had buildings in Openmine before and they're missing, see me in-game or in IRC and we can get them from a backup.
We'll need to redo the protection areas, because the move changed all the coordinates. To prevent griefing, I've disabled builds for now in the city.
Policies are to be decided, but for now, the world is creative and PVP with default fly.
The world is located at:
World name: Openmine
Server name: minetest.org
Server port: 30023
