Russ, Dave,
Thanks for responding. When I tried signing up on my iPhone 7 or MacBook PRO (2019 model), I got the error message shown in the attached screenshot, “reCAPTCHA”. When I googled a fix, I was instructed to temporarily change my IP address settings to get around it. I did this in both my phone and laptop with no success. It could be related to our miserable Spectrum (charter cable) router/ service.
Anyways, problem solved for me. Looking forward to posting a few RFI builds later today.
