You may want a FAQ section or something that describes the onboarding process a little more in depth. My gut reaction when looking at the instructions is "Will it just send my information out the second I click submit?" then I realized I didn't read the word "Create profile" on the button and that step 2 is where the magic happens.

Having something like an animated gif or screencast that walks through the process would be invaluable. It would also likely be good to have a privacy policy. I've been evaluating things like this and if I can figure out it isn't the right fit without jumping through the hoops or sharing personal information it would definitely be preferred.
