Courtesy of my friend and colleague Bhav Patel, here is a link to some great facilitation resources collected and curated by the ICA:UK crew. ICA is the global network of practice that has brought the Technology of Participation approach into the world, and this is the first time I have come across a comprehensive collection of tools that supports that approach.
I have added that link to my own eclectic collection of quality facilitation resources. That has long been the most popular page on this site!
