A recommender manages preprint evaluation. Their role is very similar to that of a journal editor (handling preprints, finding reviewers, collecting reviews, editorial decisions based on reviews), with the article eventually being recommended (or not) after several rounds of reviews. PCI Ecotoxicology and Environmental Chemistry recommenders can recommend up to five articles per year. They are expected to comply with the code of conduct of PCI Ecotoxicology and Environmental Chemistry, are eligible for selection as a member of the Managing Board for a period of two years, and can propose the nomination of new recommenders to the Managing Board.
