This is a mostly frozen copy of the Minetest forums through 2017. If you know phpBB3 and would like to host any G-rated forum here, you can email: me@minetest.org
If the email doesn't work, find out who's taken over Final Minetest from OldCoder and email them to get write access or an admin account.
I should have set this up years ago. But it's no tale of woe.
Whether the temperature is high or low, regardless of cold winds blow,
away we go like Edgar Allan Poe, on now with the show. BTW rhymes are welcome.
Mods are just Lua; if you're able to install Minetest, you should be able to copy mod folders into ~/.minetest/mods/minetest (or ./mods/minetest if you have a run-in-place version). There are several mods that you must run with the vanilla game (i.e. default), thus it is impossible to set up a Minetest server without being able to install mods.
Unless you have some kind of odd hosting plan that comes along with Minetest but doesn't give you access to the file system? I don't think anyone would expect to be able to sell that…
