I have used Tribbit before but I was reminded of it today when my daughter's 3rd grade teacher asked me for an idea on how the class could create something for a classmate's father who is serving in Iraq. Tribbit is a basic (free, of course) tool that you can use to create a tribute to someone as a way to say thank you or otherwise honor them. They describe themselves as "the online card that everyone signs." You can pick out a layout and add a picture and description to your Tribbit. Then you can invite others to leave text or audio comments, photos and other embedded files for the person you are paying tribute to. You can make the Tribbit private and only available to the people you invite, or you can leave it public. You also have the option to put a deadline on your Tribbit at which point people will no longer be able to contribute to it. Once your Tribbit is created, you can send a link to the person you are honoring so that they get to see all the nice things people are saying about them. I have included the demo video they provide on the site so that you can get a better idea of what is possible with this tool.
