I think there should be a toggle for documents that does not require a user to enter their email address to open a document. Certain ones it makes sense but others, like if you are trying to grow a product line, are hindered by the fact that you have to enter your email address to open them. I know this would make the reporting harder and in somecases not possible but for some of us it is preferrable. The other issue that is casued by having to enter an email address is if they enter it incorrectly it will create a new contact.
