What’s the meaning of the statuses?

Pending: this status will be automatically assigned to the abstract after the submission and will be used by the Reviewer every time they will add a note to ask for a correction or a change within the submission. The status “Pending” allows the Submitter to modify the abstract if needed.

Under review: this status will be used by the Reviewer when they are working on the review of the abstract assigned to them. The status “Under review” will block the possibility for the Submitter to modify the abstract.

Accepted: this status will be used when the review is over and the abstract is accepted

Rejected: this status will be used when the review is over and the abstract is rejected.
