It is a place to have the writers of your LORs send the letters. They can mail them, fax them or type them in. You cannot read them if you mark them confidential, you only see that they are in and available to send. Then when a school asks for LORs, all you do is pick the school, choose which letters you want them to get and click send (and of course pay the fee). The schools have them instantly and if they lose them, they can reprint them out.
