How is it that some of your reviewers do not know the difference between it's and its? This is grade-school stuff that any "professional" or serious writer ought to know. It's is a contraction for "it is" or "it has"; it's not possessive. This seems to be an Intternet-wide issue. So much for standards.
I always get it right since my wife has beaten it into me...
You might try sending "corrected" writings back to their creators - that might get your message across.
It's a thought...:)
