How do I create a CritViz account for myself?
Anyone can create a CritViz account. All you need is a working email address in order to verify and activate the account. Go to https://crivtiz.com, and on the front page, below the login fields, you will see a text button that says "Sign up now". When you click that you are taken to https://critviz.com/signup
On this signup page you fill in your first name, last name, and email address. Fill those in and hit the "Create Account" button. You will quickly receive an email asking you to click a link in the email to verify your account. You may then log in to CritViz.com. At first you will not be enrolled in or owner of any courses.
The email address associated with your account is used only for the purposes of user verification and password resets, and optionally for course notifications and announcements. The email addresses will be visible to instructors and assistants, but never to students in the class.
