From the Adobe Sign FAQ at https://helpx.adobe.com/sign/faq.html:

"An electronic signature, or e-signature, is a legal way to get consent or approval on electronic documents or forms. Electronic signatures are legally binding and can be used to replace handwritten signatures.

"Digital signatures are a subset of e-signatures, where signers authenticate their identity using a certificate-based digital ID, which is typically issued by a trusted third party certificate authority (such as Adobe sign) Adobe Sign manages the entire process securely, tracking every step in the signing process and capturing that information in an audit trail. Both the audit trail and the signed document are certified to provide a tamper-evident seal, and the audit trail can be used to produce evidence of each party's signature.

"Digital signatures add one more level of proof. With digital signatures, each signature is encrypted and bound to the document. Both the signer’s identity and the integrity of the signed document can be validated through a trusted third-party certificate authority. Adobe Sign supports both methods of signing in a single, scalable signature solution. Read the white paper on electronic and digital signatures."

If you want to use an image as your signature, the recommendation is to sign your name in black ink on a clean, blank sheet of white paper; sign your name in the middle of the paper so you don't photogrpah or sign the edges; then, photograph or scan your signature, making sure that the page is lit and that no shadows fall across the signature. You can then transfer the photo or scan it into your computer and upload it to Adobe Acrobat DC.

No. If you have already sent a document and need to make changes (e.g., forgot to add all forms fields to the document, or need to change a field), you can only make changes to the document in Adobe Sign if no one has signed it yet.

If the document was sent but has not yet been signed, approved, or rejected, it is still possible to edit and send again.

The recepient of a modified agreement is notified that the agreement has changed immediately after clicking the "Review and sign" button on the email they receive. The recepient must click "OK" before they can sign, approve, or delegate the agreement to acknowledge that it has changed.
