We are a Salesforce ISV and see many leads from the App Exchange. SF-IN is a click on "Try it Now".. "SF-Installation" is a completed installation. We have no way to know if the drop off from "try it now" to a completed installation is due to Professional Edition or Group Edition, which we do not support. Is there any way we can know what edition an app exchange lead is on?
And a related question -- are PE and GE orgs the majority or minority for Salesforce?
