First time
From TUTOS
When you log in for the first time you should have a look at your personal settings and learn how to modify your password and personal settings. TUTOS will jump to a page called "mytutos" 
when you login.
On this "Overview" page you will see a link which will bring you to your personal settings.
In the top part of the screen you should enter your new password.
In the lower part of the screen you can set some basic settings for your work with TUTOS.
