Take my word, I have been looking to find such a service as I have accumulated gifts to be sent to my Twitter contacts whose physical addresses are not known to me.

TwegistryTwegistry is a web service with which we can send gifts to our Twitter contacts even when we don’t know their address.

Using Twegistry, I can also receive gifts naturally.

In the long run, (why not in the short run?), only the Internet can keep the world green because, about a few million numbers of pages (A4 size paper ) are saved in text form digitally in as many number of desktops.

Similarly, thousands of greetings cards, wedding invitations and thank you cards are exchanged in the cyber space without using a small shred of paper.

There are hundreds of web sites in the internet that help us in sending paperless cards.
PaperlessPost is another website that will allow you to design your own greeting card or wedding invitation, add images and colors and send it to your list of family and friends through email.
