They are hoping to get short video or audio greetings from Scout groups around the world by November 16th so they can put together and post the final video before the event on December 13th.
The example text for the greeting is:
"Ciao Italia, Ciao Padova, we are [your name or group/association name] from [your country]. We also join your message: Together Scout to Live the Peace"Padua is located in the Italian province of Padova.
If your group is interested and can put together and post a video you can contact them at email@example.com.
I'm told they can handle a variety of formats including avi, mp4, mpg, mov, wmv, and ecc.
The 433rd will send be sending a message!
On another note, wouldn't it be nice if some of the spacecraft outreach programs would consider something similar. It would be much more interesting than just sending lists of names.
