WPOM will select its articles following a double blind, peer review process. Once the editorial team has checked that the contribution follows the formatting and content author guidelines, it is sent to two anonymous reviewers. Grounded on reviewer's recommendations, the editor will communicate the results of the evaluation to the corresponding author. The editor will communicate the overall result of the evaluation (rejected, accepted or accepted with modifications), including the reviewer's comments. If the paper has been accepted with modifications, authors should send back to the journal a new version of the article, that will be reviewed again by the same team of reviewers. Moreover, the authors can attach a letter to the editor, which should indicate the modifications made in the article following the editor's and reviewer's comments. If the authors decide not to follow a particular reviewer's instruction, they can expose in the same letter their reasons for not doing so.
