2.2 Signing Out
Signing out closes your session and ensures that subsequent visits to the site require another sign in.

To sign out, click the sign out link next to your name at the top of the screen. You will be taken to the sign in screen and a message will be displayed confirming the session was closed.
NOTE: Closing your browser does not trigger a sign out - if someone were to gain access to a machine in this state they may be capable of entering the site without credentials.
