As an instructor, you can register yourself by filling out and submitting this form. Only registered users are allowed into protected instructor areas. Include your institution E-Mail address.  This information will be kept in a registration database that is accessible only to the webmaster, not to ordinary users.  You will receive an e-mail response in a day or so with your access password.

After you are successfully registered, your web browser will ask you to type in the username and password the first time you try to access a protected area. The browser will remember this information for as long as it continues to run, so you can access any document in the protected area without being asked for the password again.
