Logging Out of New MUSE
The safest way to log out from MUSE and more importantly all the services that you have started from MUSE is to close down your web browser.
You can sign out from MUSE itself by clicking the Log out link in the left row of links. However, you may still be signed in to some of your services. To sign out from these services go to each browser window or tab in turn and either close it or sign out from the service running in it.
Logging out of MUSE does not in itself sign you out of the services you started from within MUSE.
