How can I create a server (Sky Factory 3 Minecraft)?
Either host yourself or Nitrado
But how?
Are there no free servers where I can gamble with my colleague?
10 euro a month is not much. And the free ones are rubbish
Create one on http://aternos.org/...ternos.org (it's free)
Yes is free but will not stay online 24/7 if you are not online all the time but a good idea.
