Form posts can pass repeated signer_email fields instead of signers.

}Uses your real account. The request goes from your browser straight to www.helprange.com with your API key and acts as you – this POST changes data and may e-mail people. The key stays in this page (in this tab's session storage only if you tick the box), is never put in a URL and is not sent to analytics. Do not paste a key on a shared computer.
