Thanks to a lot of work by @ericof and a little discussion at PLOG (see sprint report), we now have a Plone YouTube channel. It has a pretty homepage and the conference videos from 2013, 2016, 2017, and 2018 are all nicely arranged in playlists.
We would like to expand that with how tos, tutorials, screencasts - anything to help people learn about Plone. (As well as the 2014 and 2015 conference videos!) Please reply here or contact @ericof or me if you have a video that would be a good addition to the channel.
