Thanks to a virus and my less than stellar backup strategy, if you sent me feedback between 12/7/10 and 1/18/11, it's likely been lost, so don't expect a response. If you receive duplicate answers to other emails it's for the same reason. When I had to rebuild my hard drive, the latest backup I had for my email was over a month old.
I was way behind in my replies, but would have gotten to them eventually. Now, it isn't possible. My apologies to those I've missed.
