I haven't seen one, but I think about it a lot. Locally I'm co-coordinating an in-person group where we start meetings learning about civil discourse and rhetoric and mediation concepts, then we move on to a specific policy issue such as Obamacare, and try to make progress after being primed and equipped for civility. We're working on making a curriculum out of it. Reach out to me if you want to discuss via chat or email. I have some ideas for an online forum as well.
