This might be the most thought-provoking or 'thought-provoked' comment I've had (I have posted this on all the Fakebook pages and have had considerable response, it's surprising that there is no interest in this group.)

You bring up a good point, but I would still assert that, if you take the course and LEARN the material, it can stick with you such that you know enough to be effective AND, when the time comes to use the knowledge, you will not only have the class materials, but also the basic knowledge with which you can 'google' answers quickly. I have done almost NO component-level electronic repair since 2010 and yet, on occasions where I find myself working on a radio or similar device, I find "it's all right there". Of course, I did the work for 28 years, so maybe I am off-base a bit.

But I do think that explains some of what appears to be a lack of interest - the belief that the average person would not use what they learned. There IS some validity to that concern. It just appears (as much on Fakebook as here) that there is a desire to know more and understand more. I think I also based my guess that there was a lot of interest on the fact that I see, both here and over there, a LOT of people giving advice who clearly dont understand what they are talking about. I'd like to empower these very people to KNOW what they are talking about such that they can become an asset to the community and not do the damage they do by wasting people's time with nonsense advice. I really thought that these people would overwhelmingly respond to the offer, but Dunning-Kruger is strong, and many probably fool themselves into thinking they are giving good advice.
