    Hello, nice add-on.
    Are there more tutorials available? Many things remain unclear to me.

    How and when and where does the buyer enter his/her full name & email for example, to be stamped?

    Is there an option to let them fill in their email + name after purchase on the download page itself, to be stamped in the PDF (uploaded via WPDM via Dropbox)?

    Is there an option to PDF stamp documents that you give away for free on the website? That people only can download after typing their name + email?

    Look forward to hear from you,
    kindly,
    Steven

      “the buyer enter his/her full name & email ” — buyer’s full name and email will come from their profile info, Buyer can update those info from edit profile page
      ( For example: https://www.wpdownloadmanager.com/user-dashboard/edit-profile/ ).

      PDF Stamper Add-on can’t stamp remote file ( ex: hosted on google drive, dropbox, box.com, amazon s3 … ).

      Yes, but for now user need to be loggedin. However we shall add the support for form/email lock option soon.

    How does this plugin work exactly? Does it require a e-commerce/checkout process? I have wordpress site that requires a user to login and then they are able to download PDF documents. Is it possible that combined with downloadManagerPro that upon them clicking download it embeds their login username/timestamp etc?
