Admin advert command for Phase Four (lua)

[Typical]

I have been working on an admin advert plugin and what it does is, whenever you type "/adminvert <text>", it comes back anonymously as "[Administration] <text>"
As an example, I type "/adminvert Do not park you cars in the street, or they will be removed" it comes back as "[Administration] Do not park you cars in the street, or they will be removed" as easy as it sounds, can someone help? here is the code I have so far

local Clockwork = Clockwork;

local COMMAND = Clockwork.command:New("adminvert");
COMMAND.tip = "Sends a message anonymously from administration";
COMMAND.text = "<string Text>";
COMMAND.flags = CMD_DEFAULT;
COMMAND.access = "o";
COMMAND.arguments = 1;

-- Called when the command has been run.
function COMMAND:OnRun(player, arguments)
	Clockwork.chatBox:Add(nil, player, "adminvert",  table.concat(arguments, " "));
end;

COMMAND:Register();
