Good question. High-Value Course Academy is not a course about business basics. I don't spend time talking about how to come up with your course idea, choose a niche or build an audience. (If you are interested in learning these important foundational concepts about online business, I recommend my course Infopreneur Institute
.) While not required to participate in the course, it is recommended that you have some kind of online presence (a simple website, a blog) before the course begins. This will make it easier when you are recruiting your affiliates and joint venture partners; if they can see your website, it adds to your legitimacy.
Having an email list is always a good thing - as this will increase your immediate sales upon the launch of your course after you promote to your list. However, one of the perks of doing an online course is growing your list. So, even if you don't have one, you will still benefit from High-Value Course Academy greatly.
