To add an additional signer to a document, create or click into a document that you will require a signature on. Click on the Manage Document Signers button that you see in the right side bar of your screen. Once you do, a window will open where you can add the additional signers.
In that window, click Add New and additional name and email fields will appear. Enter in the additional signer’s name and email and click the Save button that appears to the right of the email field when you are done. You can repeat this process for as many signers as you need to add. When you are finished adding additional signers, click Done in the upper left hand corner of the window to exit back to the document.
