It is of value to permanently keep a copy of the DVD, without need of further review.
This is a computer data format DVD that can be browsed in your computer, similar to browsing the web (internet). If you have a computer format compatible DVD player for your TV, and the TV has a web browser or equivalent that is compatible, this may also be used to view the data on the DVD. (If it works.)
That is to say: this is not a video DVD that you put in and are entertained or have to listen through a long boring lecture.
There will be later editions of the DVD with more information. Some items, such as business ideas will be revealed first to those with previous editions, especially those who have helped seeding the torrent and/or burned DVDs and given to others.
The primary reason behind releasing the data on DVDs will be explained on the DVD. Another reason is that on the DVD will be a lot of raw notes, which is better not set on the internet.
Further, some ideas to improve the world, and detailed notes about the project, are better not published on the internet initially.
The DVD will be torrented out and available for download here as soon as is ready. Check back soon.
