I'm trying to do something with orders, after the status has been changed.

I have the following code in place:

public class ApplicationStartup : ApplicationEventHandler
{
    public ApplicationStartup()
    {
        NotificationCenter.Order.OrderStatusChanged += Order_OrderStatusChanged;
    }

    void Order_OrderStatusChanged(Order order)
    {
        // Get the member of this order and do stuff...
    }
}

How do I get the associated member with this order?

Is this simply order.CustomerId?
And does this represent the NodeID of the member?

Thanks in advance,

Kind regards,
