Having now read a couple of reviews of novels that I've read myself it's (1) reminded me of just how long a 500 word review is and (2) shown me that the reviews are far better and more penetrative than anything that I would be likely to produce. Combining that with the fact that my memory is now so bad that I could only produce a worthwhile review of a book within a week or two of having read it, I'm afraid that the chance of my writing any reviews is pretty slim.

Incidentally a couple of my all-time favourite SF short stories are by female writers (and I can still remember them pretty well many years after reading them), but the mention of "books" rather than "stories" in points b and c in the FAQ suggests that only reviews of novels - or conceivably short story anthologies by a single writer - are wanted. Also a 500 word review would be rather disproportionate for a short story.
