After enabling all 15 modules, a Manhattan classroom's Main Menu will look like this:

Each of the fifteen colored buttons, labeled Assignments, Handouts/Notices, Post Office, etc. represents a module. (For most classrooms, you will not use all 15 modules. You can enable/disable the modules at any time during a course using an option under the Configuration button. See Select modules for more information.)
Throughout Manhattan red stars are used to mark unread messages. In the above screenshot, the red star on the Class Discussion button means there is one or more messages in that module that you have not yet read.
In addition to the module buttons, you'll also have three light colored buttons labeled Change Your Password, Exit Classroom, and Configuration.
We'll address the Exit Classroom and Change Your Password commands, which are available to both students and the teacher, next. The Configuration button appears only on the main menu for teachers. The many capablitities available to the teacher under that button are covered in Configuration

Clicking on the Exit Classroom returns you to your My Manhattan page - that is, the page that lists all of your courses.

From there, you can select another course to enter, or you can click the Log out button to exit the Manhattan system completely.

Your server administrator determines where you go after logging out of Manhattan. Generally, you will be returned to the same page you used to login to your account.

The initial password supplied by your server administrator is only intended to get you into the system for the first time. After logging in, Manhattan will force you to change your password. After that, you can change your password anytime you wish by clicking on the Change Your Password button within any class, or on your main "My Manhattan" page.
Clicking on the Change Your Password button brings you to a screen that should be self-explanatory. There is a text box for you to enter your current password. You then need to enter your new password twice to make sure you've typed it correctly. Clicking the Change My Password button stores the new password you have entered and returns you to the page where you started the process.

You'll note the rules regarding valid passwords are quite liberal, although you'll find you cannot use your real name or your username as your password. It is your responsibility to select good passwords that would be difficult for someone to guess.
As you'll see in Reset a person's password, the teacher of a Manhattan classroom can reset any of his students' passwords to its original value, using an option under the Configuration menu. If your students forget their passwords or have trouble logging in, they should contact you for assistance.
When the teacher forgets his password, he'll need to contact the server administrator. The server administrator cannot lookup anyone's password. The best he can do is reset it to be the same as your username. Once a password is reset, the person will be forced to select another password the next time he logs in.
