How can I share my form to another account?

How can I copy and paste one of my forms to another jot form account?

If you mean to clone a form? You can use this guide to do so. How-to-Clone-an-Existing-Form-from-a-URL

But if you want to move your form from one account to another, you can send us the target username and the form you want to move.

Hope this helps.
