The review submission page is more or less similar for many different platforms such as EditorialManager, EES (EVISE), ManuscriptCentral etc.
You would find at least the following three sections after you log into the page:
- Rating of the manuscript
- Comments to the authors
- Comments to the editor
1. Rating of the manuscript
In this section, you will find pointwise portions of the assessment of the manuscript in terms of novelty, originality, writing style etc. which are related to the research work. You may probably asked to enter the rating on a scale of 1-5 or 1-10 (based on how the interface has been designed)
2. Comments to the authors
This is the comment section where you are either allowed to attach a file or enter your comments in the text area provided there. You must not be offensive in your comments. It is better to be slightly descriptive and positive in review comments which would help the authors to improve their research or the manuscript.
3. Comments to the editor
This section is confidential (mostly). Here, if you want to share something privately with the editor only, then you can. For example, if you think that the research is plagiarized or something like that. Or, sometimes, you can also praise a paper, if it worth it. This section would make the editor's task easy at least to some extent.
