Hide entered messages?

I was just wondering if there was anyway to hide entered chat strings that began with a certain substring?

Say.. oh... for example, -load?

If you could make it so that strings starting with -load were only shown to observers, it would really help prevent code cracking in games where custom save/load systems are used.

I'm not aware of any way to do that without an extrenal program. I could be mistaken though.

Only thing you can do is tell them to change to Observer chat before they load.

If you have a good save load code, nobody is going to try cracking it anyway.

Especially if you are using one of the username dependant ones.
