Video is a bit overkill ? ICT is only one person providing free work. Lots of questions are asked in live sessions and twitter/email. Im sure a screenshot followed by a question is suffice. A chart with some scribbles and text takes only a few secconds to comprehend which in video format may be a few minutes. Im sure ICT dosn't have the inclination or time to stream and watch them. If he personally mentors select individuals then video may make a bit more sense.
