When you register ClassicArray, you are supposed to receive an automated response with the registration code. I have not been able to get this working reliably, so for some customers I have been sending out the email manually. Personal circumstances dictate that I will be unable to do this promptly for much of April, so if you purchase ClassicArray and do not receive your code immediately, please accept my apologies in advance.
I will also not be able to be very active on this blog for much of April.
