If you do not have a DocuSign or Adobe Acrobat Sign account, you can still use the Signatures module with AppColl as the provider. Using AppColl has the following limitations:

• There can be only one document and one recipient per envelope. If you specify more than one recipient or document in the Add Envelope pop-up, AppColl will create a separate envelope (record in the Signatures module) for each recipient/document combination. 
• Because of the manual email signature processing, the following envelope configuration options are not available.

• Documents are sent to the recipient via email as an attachment.
• To sign a document, the recipient must print the document attached to the email, sign it, scan it, and then reply to the email they received with the scanned document attached. The reply address is a special AppColl email address that allows the correct envelope to be updated.
