Closing a GoogleApps@UIC session is a two step process. You must do both.
IMPORTANT WARNING: Just closing the Web browser (e.g. Firefox, Internet Explorer, etc.) or just clicking the Sign Out button will not end your session. The next user who comes along will have full access to your GoogleApps@UIC account. Always do both when you are using http://gmail.uic.edu on a shared computer.
