All you are required to submit for an account is a username and email address. This will allow you to start submitting case studies and commenting on existing case studies. Your information will not be disseminated.
Although it is not required, you may enter Authorship Information which will appear on case studies that you submit. This will only be shown on the print-friendly versions of the case studies which are only available to you and other registered users. This feature is included so that you may create a publish-worthy final document for your records. Authorship information will also show on your My Account page which is only visible to other registered users.
