I think that there needs to be a forum in which to discuss complementary currency topics. Since the deaths of Stephen Belgin and Bernard Lietaer in recent years, there really is no one "authority" on complementary currencies.
The world needs one! In my view, a great place to start creating such would be with a combination of successful initiatives such as this one, Ithaca Bucks, etc., guided at a theoretical and historical level by the "great work" co-authored by Belgin and Lietaer, New Money for a New World, edited by Jennifer Dunne.
When we create a new model society, complementary currencies will be "wired" into the design. But that is still years away.
