I'm really persnickety about spelling, grammar and punctuation and used to love it when I found mistakes in the publications.
I have to admit that I didn't find many spelling mistakes. There were a lot of grammar and punctuation issues though; too much use of unnecessary exclamation marks used to get on my nerves especially.
It's a good point about passive sentences Reckless. I remember from my college English class that many businesses, politicians, educators etc use the passive voice to avoid responsibility for actions taken.
A lot of grammatical errors and strange sentence structure in the mags I often put down to being an American way of forming a sentence. Maybe it was just plain wrong after all.
