As a reminder please note that some wordprocessing systems (e.g. Word) will include a document authors name in an author field for a file. This is important if you are going to upload an attachment from a wordprocessing system with your review. A word file when converted to PDF will have this author information.  Please make sure you do not include this information.  You can check a PDF upload to see if it is included by clicking on file, document properties, summary.  It is also possible to click on the little right pointing triangle above the page slider on the right of the document to get to document summary. The author field should be blank or clearly not the name or any information that could identify the reviewer.
