The log file approach seems promising. Worth asking Adobe Support, even if to enable logging for only a couple of hours (I can probably check to see if there's a pattern with previous signups to get the "most popular" time of the day that they're coming in).Great idea with the JS code! Maybe something like document.referrer could work. Let me try this on a test web app and see what turns up. Thanks so much!Sonny

Thanks, Vipul. Both options sound good; definitely worth a test or two!Sonny

Hi Danny (and Florent),Never got back to this...we had the Mac peeps install Parallels, and then Win10.So, it is workable now.Thanks!Eugene

Thanks, Florent. That's too bad; it seemed like a convenient option for Salesforce integration.Sonny

Hmm.. interesting. Thanks, Florent!Sonny

Thanks, Florent. Glad to know it might not be something I've been doing wrong! 🙂Sonny
