Contact a suggested referee
If the journal requests this information during submission, you will have the possibility to invite the referee(s) suggested by the author.
Or Declined referees can also suggest their own colleagues to help you find an appropriate expert.
In any case, Nestor will check if the suggestion is already present in the data base. In this case, you can just click on "Invite" to trigger the invitation. Otherwise, you will need to create the referee in the database.
