How to send to clients without their responses changing original form?

also do clients have to have an email account to fill out or can I open a link that can save their submission seperately?

I'm sorry, but I'm not sure I understand your question. Do you want your clients to fill and re-submit their initial submission so they don't need to resubmit a new form? If so, you can setup an autoresponse email and put the {edit_link} parameter so clients can resubmit it later.

If that is not what you had in mind, please clarify. Looking forward for your response.
