1) No, you can't delete your own reviews, or even aspects of a review. It's a setting for all authors. If you need us to delete your second review, let us know.
2) I'm confused by your question. Is your fiction still in queue? If it is, sit tight and we'll get to it. If it is no longer in queue, please feel free to post in the missing letter thread (if you did not receive a letter, of course).
