When a manuscript is listed as "In reviewer agreement" in a journal's status, it means that the reviewer or reviewers who have been assigned to the manuscript are currently discussing their opinions and trying to come to an agreement about the submission. This process is part of the peer-review process, which helps ensure the quality of the papers the journal publishes. During this stage, the reviewers discuss the merits and weaknesses of the manuscript and provide their feedback to the journal's editors, who will ultimately make the decision about whether to accept the paper for publication.
The status "In Reviewer agreement" typically means that the manuscript submitted to a journal is currently being assessed by the journal's editorial team to identify potential reviewers. During this stage, the editors are actively searching for and contacting potential reviewers who have the expertise and knowledge relevant to the subject matter of the manuscript.
