Hi Christian,
I really appreciate all the documentation, videos and responses here. Unfortunately, there must be some problem. I did get the free PayPal to work, however, it registered me as a Participant and not an S2 Level 1 member. I didn't do the original install, but I did perform the Pro install. (We have the Pro installed but the site owner is not ready to commit to PayPal Pro for CC processing). I'm just reporting the status. Maybe if we later switch to using pro forms, the issues will be resolved. Thank you, Hank
