Hi,
I think there's a bug on your registration page. When I enter my email and click on "Get Studying" nothing happens and the mouse arrow just turns into a circle
Maybe it is working but the feedback just isn't clear enough? It should output a success message/error message below the Get Studying button. (And then you'll be sent signup details in your email)
"Cool, you're all signed up! Check your email for your invite code."
