Which mod is it that allows for commands to be issued from the client in the world chat? And how do I disable that?

Or point me to the thread where this has been answered!

Thanks in advance!

What? you mean commands like /op etc? thats just normal mine craft if you don't want anyone to use it don't give them op. It could also be a plugin, you need to set permissions for those.

Yea commands to like change the time and give items just finished disabling NEI and well I pulled up the chatbox on my client and was able to change the time give myself a stack of items etc etc. Now I'm trying which perm's I need to set or what plugin needs to be changed! Thanks for the tips though!

if its /give its hard to change without a plugin if its /i its a plugin and changing the time is a default server command.
