When a user sends a request to access restricted files in a dataverse, an e-mail notification is sent to the address or addresses that are specified by using the Set Contact Us E-Mail option for that dataverse.
You can specify multiple e-mail addresses for the Set Contact Us E-Mail option by using comma separators. This means that you could add the e-mail address of the Contributor who uploaded the study in this field, and that Contributor would receive e-mail notification when a user requests access to restricted files in that study.
