As mentioned at the beginning of this lesson, notifications are messages from Facebook to alert you to stories or activities that involve you somehow. If a friend tags you in a note, for example, or joins your group, you’ll see a notification. Some applications you use also automatically generate notifications concerning you. You can view a brief listing of notifications by clicking the Notifications icon (a globe) in the upper-left corner of the Facebook page (refer to Figure 5.2). The icon often has a red number that pops up next to it, indicating how many notifications you have waiting to be read.
For a full-on display of all your notifications, however, you need to open the Notifications page. Click the Notifications icon, and then click See All Notifications. This page, similar to Figure 5.9, displays notifications sent from you or received from others.
