When your submission is under consideration, you can keep an eye on its status by logging into the website and going to the Submissions page. You can see that it is currently in the Submission stage.
Over time, it will move into the Review stage, and if accepted, into the Copyediting and Production stages before being published.
During the review stage, you'll see a status update at the top, which will keep you informed as reviewers are recruited, assigned, and submit their reviews.
During the review stage, you may be asked to submit revisions which address any concerns raised. If needed, you'll find a Revisions panel where you can upload new files for the editor.
