Hi, I have been disconnected from ServiceSpace since I moved out of the Bay Area, but I have never forgotten and would like to reconnect and I ask for your collective knowledge for my project. I have started working on a video project about how the idea of paying-it-forward has worked historically and what makes people Pay-It-Forward ideologically as well as practically on an individual level as well as on a systemic social level. I am looking for examples of organizations which have successfully run Pay-it-forward operations. Some of the examples I am aware of are: Churches, maker spaces, Karma Kitchen, and Vipassana retreats. I would appreciate if you could add to this list some other examples which I will use for referencing in my project. Thank you!
