Released May 11, 2010. The Gaia Ecard is a Gaia themed personal message that can be sent to friends using the "Flaunt it" feature.
copied verbatim from announcement
If you’ve got it, flaunt it—and now we have a new feature to help you get the word out!
When you save your avatar you’ll have the option to send an ecard with a snapshot of your newest look and a personal message. Don't keep all your cuteness to yourself; that’s just greedy.
