I have built and mentioned this site a while ago, but no visitors. It is sort of a personal experiment and I am waiting to see what happens. No big hopes anyways.
The idea of GreetingCardBuilder.com was born out of realization that e-card sites do not allow enough customization on the cards and therefore the cards lose the personal touch or true meaning of the message they intend to convey. What better technology than Flash MX to create a greeting card building application, giving you the flexibility to change any or all aspects of the card?
