File Requests: View the email of the user who submitted a file

If no email address was submitted, then I wouldn't expect DB to share one, obviously.  But if the sender did provide one, then why would it not be shared with the receiver of the file?  That's the question and issue.  Making the email address of the sender available to the receiver would help immensely for people working in databases, like myself.  An email address is a more absolute piece of data than a name, thus easier to search and match a received file with it's owner.
