        This extension provides a plugin that displays a double-opt-in form.
        Successful double-opt-ins are saved as TYPO3 objects in the database
        and can be exported using standard TYPO3 backend functionality.
        The extension is especially useful if you have to retroactively
        double-opt-in email addresses (because DSGVO coerces you to do this):
        Just implement the form and have your users/subscribers fill it out.
        You can also use this extension to force users to double-opt-in before
        downloading a file.
