How do I share my form with another JotForm user

You can have other user clone your form: https://www.jotform.com/help/27-How-to-Clone-an-Existing-Form-from-Your-Account

If you want him to have your form under his account then use the above cloning.

If you just want to share your form URL to him you can find the URL by following: https://www.jotform.com/help/401-Where-to-Find-My-Form-URL

Let us know if you have any further questions.

Thank you!
