I got one review on the 16th. I don't think I got any on the 17th. :(

I often wonder if the required review is keeping people from leaving a rating. In the past, I got more ratings when you didn't have to leave a review. There's a definite benefit of having the review though because it can bring up issues that you didn't know about and provide a way to communicate.

What I've found is that people who are unhappy with a plugin are sometimes more likely to leave a review than people who are happy. I believe this can change if we have some sort of mechanism for doing reviews from the WP admin.
