Answer
Click on
eCards in the top nav.
Click on the eCard you want to send, click the "Send this eCard" button.
On the next page, enter the username of the person you'd like to send to (you must spell it exactly correct). You can also choose a user from your favorites list that will be loaded on that page.
Next type in your message, and click "Send eCard". If you want, you can also change the way the card looks (the colors, font-styles, etc.), and you can also change the music.
