In case of conflict of interest, you should choose, as soon as possible, the option Decline Review.

If you intend to re-assign the paper to another reviewer, you may choose the option Suggest Another Reviewer => . In this case, fill out the field on the same line with the e-mail address (login) of the chosen reviewer. He must have been previously registered as a reviewer.

In order to find who are the registered reviewers, you may use the  'Search for a Login'  in the top green frame.

If you don't find the desired reviewer, you should ask him to follow the same procedure that you use to register yourself.

VERY IMPORTANT: Please, before assigning a paper to an external reviewer, contact that person informally and confirm that he/she is willing to review the paper.

If you have finished to fill out the review form, you must choose the option Send Review.

Living this field with the option Save Review and pressing the  'Update'  button, the form data will be saved and you will be able to return any time to continue reviewing the paper. Otherwise, (i.e, choosing any one of the other options and pressing the  'Update'  button) you will no longer be able to return to this form.
