I have been invited to review a manuscript written by several authors. One of them has been the editor of one of my recently published papers. This is the only interaction I have ever had with the author of the manuscript.
Would it be OK for me to accept the review request?
While I personally do not see anything wrong with it, it might be the case that I am positively biased towards the paper, without realising it. Hence my question.
Bonus question: the journal adopts an open peer review system, where the reviews and the reviewers' names can be published alongside the paper. Shall I accept the review request, would it make sense to disclose my concern in the review I submit? Assuming that the paper gets accepted, of course.
