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. Regards. -- Tim Johnson <[tim--johnsons-web--com]> http://www.johnsons-web.com
