Is it a money issue with the server? if so my old computer has been sitting around doing nothing/off for the past 2 years or so.. I'd be willing to use it as a server if that is possible for Midgard. No idea if it's capable so here are the specs

I'd definitely just let the server keep running when I quit unless no one played there anymore at all, even then I might leave it up. I have no idea anything about how to run/set up a server though, so would probably need someone to teamviewer in to take care of that as well unless it's easy.(I set up a custom ark server on it for me and my friends at one point but that's easy stuff)
