+<h3>Workshop: Commotion Wireless</h3>
+<p>Commotion is a project that helps communities use cheap wireless
+hardware and open-source software to build their own network
+infrastructure. These networks can help spread cheap internet access, as
+well as provide a powerful alternative to traditional networks through
+providing local services, local ownership, and resilience. At this
+workshop, one of Commotion's developers will walk participants through
+the process of organizing, designing, and building their own networks.
+Additionally, we will talk about the technology behind community
+networks, and the rich history of such networks throughout the world.</p>
