On the information page of my article submission, there's a column titled "ADM", listing the name of two persons that I can email.
What does this stand for?
ADM, most probably stands for Article Dedicated Manager, not sure though.
ADM is a person in-charge of handling any communication about a specific article. His role is to answer general questions and to give advice to authors. In some cases to communicate with editors if questions require that. However, decisions of accepting or rejecting articles are usually made by EIC or other Editors in the editor board.
