Thanks for sharing. I took a look, and found some things that I've forgotten.
Like you, I've went through some of the same struggles using the Brain since its 3.0 days, and have found some of the same resources helpful (Jerry's Brain, Omer's Webinar, etc.).
Part of the Brain's strength lies in it's community of users, who are willing to share their experience with one another.
Thanks for sharing yours.
