Hi Donald: You're preaching to the converted, but the sermon is
well worth hearing again from time to time! :>)
Actually, I have a client who is using eSignal and wants to
put data that he actually subscribes to and pays for into
a format that eSignals can't do for him.
One of my approaches to this would be to intercept the data
first (if I could). This is the foundation for my question.
any other ideas?
I won't have time to get a copy of eSignal and test it out
unti monday, thus my post to this list.
