The easiest way to see a list of documents sent for eSignature is to click Manage under the e-Signing title in the Dashboard. If you can't see it on the dashboard, you don't have access rights to eSigning (please ask your account admin to give you the access rights).
In the Manage page, you can see a list of documents yet to be signed under the tab Awaiting Signatures. Finalized tab shows you all the documents that are already signed. Depending on your access rights, you can see a list of documents you have sent for signature, or all documents sent for signature in your account ("See eSigning documents" access right).
