Looks really good and I like that you don't have to create an account. I didn't run into any major issues. Just a few thoughts:

- I found the copy after "Try a demo" a bit confusing. I wasn't aware of the concept of creating the form by sending an email, so the first sentence didn't make much sense initially. Maybe make the "To get started, copy the example text below. " more prominent and break up the "We'll reply..." sentence into something shorter.

- Once I've created a form and go to the homepage, could you show a link to it on the homepage?

- When I got the email to fill out the form I wasn't sure if I was supposed to edit the quoted text (even though that's exactly what you were telling me to do). Maybe add a link to the web form just in case.

Keep up the good work!
