This request must include:

The reason the name should be added or removed, or the author names rearranged and
Written confirmation (e-mail, fax, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.
Requests that are not sent by the corresponding author will be forwarded by the Journal Secretary to the corresponding author, who must follow the procedure as described above. Note that: (1) the Journal Secretary will inform the Journal Editors of any such requests and (2) the publication of the accepted manuscript in an issue will be suspended until authorship has been agreed.
