\label{Roles_screen}
After logging into LON-CAPA with your username and password, you will
see a screen where you can select your role. LON-CAPA is a roles-based
system. You can always use the same login even though your roles may
change. You can be an instructor in one class, a TA for another class,
and an author of resources with the same username. Selecting ROLES
on your Remote Control or on the Main Menu will bring you back to
the Roles screen. For students, the word ROLES is replaced by the
word COURSES.
