To view your past notifications, click Menu > Notification Center.
The Notification Center has all your notifications from the platform (in case you miss one and need it later). These include:
- Comment Mentions
- Comment Likes
Click the Mark all as Read link at the top to remove the green "new" indicator from the notifications. Click the down carrot (V) in the upper-left hand corner of each notification to hide it.
The Notification Center will show the last ten notifications. Scroll down and click the Show More button to see the next ten.
