Write to Jeff.

Got a question about the book, got stuck on one of the machines, or built something with it? Tell me. I read every message myself. There's no assistant and no auto-responder.

What's this about?

Message If you're stuck, name the chapter and the tool. "Chapter 7, the Make.com step after Kit" gets you a much faster answer than "it isn't working."

I'm fine with Jeff replying to me at this email address. It won't be added to any mailing list.
