Check out Gutenberg.courses!
Our friend Zac Gordon rushed home from WCUS and made a great course (I’m still working my way through, but so far I’m impressed) about developing your own blocks for WordPress’s forthcoming Gutenberg editor. He published it just a few weeks ago, and he’s still got a launch discount available thanks to his sponsors, which is very cool.
Zac’s also a very giving and collaborative guy, so he also pulled in the course from Joe Casabona to share the marketing stage on the site. Joe’s course is for people trying to come to terms with the editor and how to use it. I’ve not seen it myself, but if Joe’s earlier work is any indication it’s well worth the (steeply discounted) launch price of $13, and the normal price of $39.
