Manhattan is a private system protected by a username and password.
Your username is the first letter of your first name, followed by at most 7 letters of your last name, all in lowercase letters. Initially, your password is the last 4 digits of your Social Security number. Find and click on your course in the list, then enter your username and password. Manhattan works well with recent versions of either Microsoft's Internet Explorer, or Netscape's Navigator web browsers. If you are an AOL subscriber, first be sure you are using a relatively recent version of their software at least version 4.0.
