hi T,
Click on the Theory and Circuits options on the top Menu bar.
Members have posted lots of useful info, along the lines you are suggesting.

Yes, I looked at those after I posted my idea. I actually like the "Circuits" section. Nicely divided into topics, or chapters. Could it be possible to add "Programming" section if there was an outline of the content and a plan how to manage it? And would it be possible to add rights to modify the articles to multiple (trusted) members? .. Maybe this should be discussed in the site issues and feedback forum.
