Ah, now I see. I couldn't understand why you were posting this question here and gave you an overly detailed explanation of how to open a new thread which, despite your generous characterization, was actually Not Helpful.
But here's a suggestion: if Book Crossing is ok with it, you could just post a
link to your Epinions review along with a brief note that your impressions of the book can be found there. That, needless to say, is quite all right with Epinions

and might kill a few birds with one stone.
