For all users, there is an email update option, which results in the user being notified by email of each new issue's Table of Contents. For journals operating in more than one language, Reviewers can indicate in their Profile the languages in which they are comfortable reviewing submissions.
When you register the system creates a "User Home" page for you which make it easier to access your journals. You must register if you wish to submit a paper to any journal or if you will be a member of the editorial team (eg, editor, reviewer, proofreader) of any journal.
Some journals restrict access to some portions of their site unless you are registered.
How do I register?
You can register by clicking on "Log In" or "Register" on the site home page or on any journal's home page. Alternatively, you can ask a Journal Manager to register you. Contact information can be found in About the Journal.
You create a profile (including a username and password) when you register. You can edit your profile any time you are logged in. In the right navigation bar under the title "User", the link "My Profile" appears; click on that link and you are taken to your profile. Here you can change your contact information, reviewing interests, roles, and can manage email notifications for journals you have registered with.
