Notifications don't appear in notification center...

[GCardoso]

Since I installed ML I've received like 20 notifications, mainly from twitter and mail, they pop and click on them to go see the tweets, but when I return to Notification Center there's nothing there... are they supposed to not show up after I click them, or am I doing something wrong???

You are correct, after you click them they disappear from the Notification Center.
