Nope there is no whitelist on the server. I figured, there is Server Utilities installed, so any player can just claim their chunks if they fear griefing. And I believe that the people here are nice and not douches 
But time will show if I can just accept the whole internet to join the server 
Fast leaf decay is inside, because somehow the GT config only works for GT trees, maybe due to a collision with some other mod? Or maybe I’m dumb 
And yes, it has a touch of kitchen sink, because I don’t want to purely play GT 6 and instead mix the gameplay a little. Maybe that makes things more interesting. My last game-through was pure GT6.
