Have you heard of The Graditude Campaign?

I got this in an email from a friend.

This is pretty neat. . . . . . . . Have you ever seen one of our military walking past you and wanted to convey to them your thanks, but weren't sure how, or it felt awkward?
Recently, a gentleman from Seattle created a gesture which could be used to express your thanks and has started a movement to get the word out..Please everybody take just a moment to watch..... The Gratitude Salute
...and then forward it to your friends!
THEN START USING THE SIGN.
