I downloaded it then tried it out. Nothing happend, so I looked for commands and there weren't any. That was dissapointing because had I hoped for nice weather with this mod, but there weren't even commands I could use. So I suggest making the commands that you say there are but I dont see work, or making the weathers happen more frequently.
Hey, that's harsh! :( I redownloaded it and it doesn't even have the command! I looked in the code and found there was a command but when I tried it in the game it didn't do anything it just said it was invalid command. I DO know how to use minetest!
