The webinar is a learning resource for activists who might like to apply some of the principles of disaster management (and lessons learned); students/activists can apply the info toward managing support systems for large-scale protests or encampments (particularly for sustained protests).
You'll need to register for the webinar through Adobe Connect, here.
People who've gone through CERT or NET (Neighborhood Emergency Teams) training will be very familiar with the terminology, but if you don't have direct experience with either CERT or NET, the links below will provide you with a quick overview.
Please note that both CERT and NET are related to the Federal Emergency Management Agency, which is a function of the U.S. Department of Homeland Security. If you'd like to visit such sites without undue concern about being tracked online, consider downloading the TOR (encrypted) browser here (and you'll need to follow TOR's instructions about safe browsing).
