My Blog's Facebook Page - now with Sign-up button :) -
After completing Diego's tutorial; I've managed to successfully set-up a Sign-up button on my blog's Facebook Page ( https://www.facebook.com/lifeineight ) with a re-direction to my current opt-in landing page (Where I give away a gorgeous Weekly planner printable). This is the landing page by the way http://bit.ly/2dwXpfb.
I'm yet to update my opt-in and landing page so that will be the next stage. I'll report back once I've done it :)
