When a law review extends an offer to an author to publish a manuscript, this is called a "publication offer".
Authors can accept or decline a publication offer by visiting an individual submission page. To do this, click "My Manuscripts" and then click Manage Submission. Here, there will be a list of the journals with a green publication offer button under the journal that has made the offer.
Editors can change the publication offer deadline by visiting the individual manuscript submission page, and clicking the "edit" link next to the publication offer deadline date. Editors can choose to send the author an email with the updated publication offer date, or editors can choose to not send the author an email (e.g. if an editor already spoke with an author by phone).
