I did know that Youtube is revamping it’s Creator studio, which I have Beta access to, and am quite excited to see the full version of, but I was unaware of this. Apparently, they had put out a notice (not very widely apparently) that is was going away permanently a few months ago. A very useful tool that I found out this morning (when I logged in to Youtube) that it’s being retired on September 20, 2017. Today I was supposed to teach a short instructional webinar on using Youtube Slideshow Creator.
