Hi guys, not having found a better thread title a short description of my problem: How can you disable the menu on the right site of the inventory screen where you can give yourself all possible blocks. This, for the lack of a better word, "cheating" really took the fun away. I already tried corporal punishment and deactivating NEI in the modloader.cfg on the server. Neither of which solved my problem. Thanks in advance Garfield
