I do appreciate you stopping by and reading this piece! There are no immediate plans at the moment for a part 2. Though, I know I will be revisiting this topic again in due time since it is so personal & near to my heart.
I am actually unsure about that. My site didn’t originally have CAPTCHA (that I was aware of), and I believe that it was etched in at some point during one of my sites automatic upgrades. If you click on “Dashboard” and scroll down, you should see a “Plug in” tab. Click on “Add New”, and then search for CAPTCHA there. Hope that helps!
