Re: [Pharo-project] State of PharoConf videos

by Christoph Wysseier

Hi Stephan I would like to show my talk ("Selling Pharo-based Solutions" at PharoConf) to my team and enhance it for the next time. Just out of curiosity: are you still working on those videos? Otherwise, would you mind to provide the video file somehow?
