Another "rate my server" thread

Hey everybody. I've recently opened up my server to the public, and I was wondering if you guys could shoot me some feedback on what could be better. It's a simplistic PVE survival server with a few minigames on the side. They're not meant to be the main focus of the server, just something to do with some friends when you're bored of building.
