Sign Out of a Site
Scenario/Problem: Sometimes when you are viewing a SharePoint site, you might want to sign out. For example, say that you logged on as a different user, and you now want to sign out completely.
Solution: After you have logged on to a SharePoint site, you might want to sign out. You do this by clicking the [your name] link at the top of the page to open a drop-down menu and then selecting Sign Out from the options (see Figure 2.3). After you click on that option, the window shows a message that you have been signed out, and it closes itself if your browser allows it to.
