A: To fill out a form before sending it for signatures, you have two options:

Use the "Prefill data" feature
On the Create New Request page, scroll to the bottom and click on Prefill data. This lets you enter information into the document before it reaches any signers.

Use the “Sign Myself” and “Sign in Order” options
When setting up the signing request, enable both Sign myself and Sign in order. This allows you to open the document first, fill it out (with or without signing), and then have the system send it to the next signer automatically.
