Registration is required for all authors and readers. See the JCSE Privacy Statement if you are concerned about the uses to which the information that you provide will be put. Items marked with an asterisk (*) are required.
If you have already registered, and you just want to change your email address, please do not create a new account, as we have no way of knowing that you are the same person. This is especially important if you are a paper author, as your new account will not be recognised as belonging to an author, and you will not be able to respond to comments on your papers.
