Thank you so much for sharing your expertise and links to others. I checked out your link, took a brief look at a Charles Dowding video and he seems really good. He definitely has an educational demeanor and his showing examples, comparisons, etc has got to be a time-saver in the end as he's not just telling you about great methods, but he's showing you clearly marked versions of what he's tried, what works, what didn't. Your information is greatly appreciated. I'll check out the others you suggested as well.
