So you would like to attend one of the presentations of the FSDevConf? There are two ways you can view a session:
Either through the FSDevConf Google+ page or through our YouTube channel you will be able to find the session that are being live broadcasted during the conference. Just go to the channel at the time of the session.
If you view via Google+ the advantage is that you can ask questions directly to the presenter using the Q&A module of Google Hangout.
All presentations will remain available on YouTube after the conference as well, so you can always watch them again on the FSDevConf YouTube channel.
