By sending and receiving gifts from your friends, you can build up a collection of fun, animated items.  A new gift item is featured every day, and a gift is available for only that day, so you'll want to log in regularly to send them to your friends...  and ask them nicely to send one back to you!

To give a gift, click on the "Give Gift" icon in the Flash application header bar.  A pop-up of the animated Gift of the Day will come up.  Click on "Send Gift" and select your lucky friends.  When you have selected all of your recipients and click "Send Now", an email will be sent to your friends, notifying them that they have a gift from you!
