I've been told that adding "no-z-fly" and "no-z-cheat" to the motd on your server can disable the use of both flying and cheating on the zombe mod. The problem is I don't know where I should add this. I've tried adding a motd.txt to my server root directy, and adding "no-z-cheat". I've tried adding "no-z-cheat" to my server.properties file, but no luck. Can someone help me disable this on my server?
