We have received some questions about the livestream videos from the 2015 conference. Sadly we only had a free Livestream account, so they do not provide dedicated storage, so they videos were only up for about a month. We have low-res copies of the stream sessions, as well as some better quality of the keynote with Michael Hardt and others, which we are working on uploading and will post here once done. Sorry to everyone looking for those videos at the moment...please bare with us!
