Dear all;

I have a paper with a status was "under review" on May 25 (2015). The status changed to "reviewers assigned" on Sep 2. The current status is still "Reviewers Assigned" (two months ago).

PLZ, can anyone help me about how can I ask the editor regarding this change...

Thx

It probably means that the reviewers they initially asked declined the invitation to review and they assigned new reviewers.
