            GetPlayerName(playerid, name, sizeof(name));

            //SendMessageToAllAdmins(string);
        }

}

obviously replace the //SendMessageToAllAdmins with your function to send a msg to all admins...
If you want a complete working system, you'd better use the script request section.

example for sending a message to all admins

                SendClientMessage(i, 0x99999AA, text);
