Well the video last week opened the flood gates with questions and comments on the subject of shorts and what can be done about them. Consequently I decided I needed to address those questions and comments and provide some more information in this followup video. I mentioned I would provide several links here and those will follow. Below those are the time stamps for the horizontal scroll bar "chapters" I discussed in the video so you can just ignore them.
