E-card - online puzzles

An E-card is similar to a postcard or greeting card, with the primary difference being that it is created using digital media instead of paper or other traditional materials. E-cards are made available by publishers usually on various Internet sites, where they can be sent to a recipient, usually via e- mail. It is also considered more environmentally friendly compared to traditional paper cards. E-card businesses are considered environmentally friendly because their carbon footprint is generally much lower compared to paper card companies because paper is not used in the end product.

E-cards are digital "content", which makes them much more versatile than traditional greeting cards. For example, unlike traditional greetings, E-cards can be easily sent to many people at once or extensively personalized by the sender. Conceivably they could be saved to any computer or electronic device or even viewed on a television set, and digital video E-cards have begun emerging.

Typically an E-card sender chooses from an on-line catalog of E-cards made available on a publisher's web site. After selecting a card, the sender can personalize it to various degrees by adding a message, photo, or video. Finally the sender specifies the recipient's e- mail address and the web site delivers an e- mail message to the recipient on behalf of the sender.
