RE: [TCML] Comments please: Book review
I'm not an English major, just an "other."
I would say that this review will be used as a summary of sorts for advertising purposes and such? If so, it might pay to leave out the personal experiences with different caps and just make a mention that information on DIY caps / MMCs is available elsewhere (a perfect time to plug the TCML. . :^)
Also, when writing a review, you should NEVER mention that you didn't finish the book! I remember doing book reviews back at school, with the teacher asking, "Did you even read the book?!?!?"
Usually ended in a fail. Just a thought. . .
Also, I have taken the liberty of correcting a few typos and making a few substitutions. Not sure if I picked them all up, but I think so. I could be cheeky and say you spelled organized wrong, but I am Australian (We spell it "organised.") ;^)
