Hi,
Thank yuo very much. I will think about it deeply in order to apply it in pratical. Thank you.
I have another question too, As I read from FP advisor, the author of admin-manager will create comserver as many as comclient instance then store the client reference on each comserver property and stire the comserver to a public array. Why we need to have so many instance, instead of have a single instance of comserver, and just store the comclient in array. Once necessary, call the client store in array?>

Thank yuo
