Hide @command of GM

[Hadeszeus 15]

Hi Guys, just want to ask if it's possible to hide from chat when someone type a GM command that is not available for normal player or in group id 0?

Example:

Player A [Group ID 0] type in Normal, Party, Guild Chat any GM COMMANDS 

Like for example Player A type @allstat <-- @allstat should not appear in Chat Box it's like nothing happen just ignore it from displaying.


Thank you..
