Group Signed Greetings and Tribute eCards
Tribbit is the first site I've heard of that lets you create group ecards and tributes that you can then send on a specific date. Everyone can make changes and additions to the eCard to go along with the message when it's sent.
First you set up the eCard to be sent on a specific day. Then you email everyone you think might be interested in helping with it. Then every one of them can add words, pictures, videos and audio messages to go along with the message.

It's not just for creating eCards though. You can create tribute pages to someone you love too, or about something you feel strongly about.
The tools that Tribbit supplies you with will let you add photos and other graphics, add text, add videos and voice messages. Voice messages can be added using the telephone, now that's what I call easy.
When you're all finished you can share your groups creation at an event or even buy it and keep it as a keepsake.
