A few friends and I started a server together and I'm the admin. We all went creative initially because we wanted to build up a neat house to live in but now the plan is to switch to survival mode and go from there. My questions is, is there a way for me to check what mode a player has thier NEI set to (survival, creative, creative+) because if I deop them and they're still in creative mode then it just locks them in creative mode. Alternatively is there a way to force them out of creative mode with a server command?
