I am currently running a Revo server at the moment. It started as a project between friends! We were really disappointed with the current state of iRO Re:Start, so I decided to create a "dream" server that was almost close to the ideal of what we wanted for Re:Start. I can tell you straight right off the bat if you don't know what you are doing, you are going to be an autodidact because there's no official "Revo Classic" code out there. You'll find yourself in a position when you're on your own most of the time. Even so, I am happy with the current results of my Revo server.
Right now, iRO Re:Start is just a nostalgia cash grab with a terrible WoE community. All they care about is numbers and who makes the weekly attendance for the next WoE drama session. There's almost no PvM/MvP scene and the maps/areas that are decisive for a PvM community are destroyed or extremely gimped. Even if our server does not become the next thing, I am happy I was able to provide a haven for those who were looking for a Revo alternative.
