Since I've just arrived in PB family just about a couple of months ago, you'll forgive me if I am to post a reply to a post 2 years old... But I can't help it. Although I completely agree with you, Nolan, regarding 'giving advices how to improve' I also support the constructive criticism. I usually don't say anything about someone's work if I can say something nice, but I believe that sometimes, it's very useful for the learning process to hear some 'bad' opinions too, if they are given with some solutions too. Anyway, I think you are doing a wonderful job and finding PB is just about the best thing that happened to me this year!
