Text Box for Reports
If you prefer to work offline, you may find it faster and easier to download and print the manuscript, draft your review remarks in plain text or TeX, and copy and paste into the referee remarks text area on this screen.
NOTE: As a referee, you have the option of attaching a file to deliver your report. It is recommended, however, that you instead use the text box on the Referee Recommendation Screen to type or paste plain text or TeX code. PDF and Word file attachments sometimes contain hidden information that reveal your identity. If you must send an attachment know that it may be forwarded to the author by the review editor, so please be sure to first edit the file for profile information that, if left in place, could disclose your identity as the owner/creator. See more information on finding and removing identity clues in referee reports.
Private Message to the Editor
There is also a separate text box available if you wish to include a private message to the editor. A point that is not meant for the author should go in the box labeled "Private Message to Editors." This is found directly below the "Detailed Comments" text box where you enter your report. The "Private Message to Editors" text box is optional, and should be used only for items not to be forwarded to the author.
MMS authors are encouraged to submit Supplementary Materials to complement articles. They might include additional figures or examples, animations, data sets used in the paper, computer code used to generate figures or tables, or other materials that are necessary to fully document the research contained in the paper or to facilitate the readers' ability to understand and extend the work.
If you are refereeing a paper that does include Supplementary Materials, along with the manuscript, know that the Supplementary Materials are generally not refereed but are available to you, as a referee. As part of your review you are asked to give the materials at least a cursory look and verify that they are appropriate to accompany the article. You may suggest changes, including removing some extraneous Supplementary Materials or moving items from the main text to the Supplementary Materials.
The author is also asked to submit an index of the supplementary materials. You should find a listing of each item along with a brief description and a justification for why the item should be included. This should be helpful in judging the appropriateness of the materials. Full guidelines on the journal's Supplementary Materials policy are available here.
Author Rights to Unpublished Manuscripts
All manuscripts are privileged documents; an author retains the right to the unpublished work. A referee should not use results or ideas obtained exclusively through the refereeing process in his or her own research.
