Aimee,
I read through your privacy policy and find it to be near perfect.
What I say next means nothing to me personally, but it might mean something to a select few whom I believe are the people you are addressing in the first place.
As forum members, our "forum activity login time and usage" statistics are made available to the PC community in a very easy to understand graph. I feel that publically available data would be considered private information by "that select few", so it might be a good idea to mention that graph in your privacy statement. I love the "Stats" page and hope you don't do anything different with it.
Just a kind suggestion, not a request.
