You probably already saw the sad news that Dpreview is shutting down. I have to say that I am not surprised. Amazon would not keep an entity alive if they do not contribute to the bottom line. I was actually expecting this to happen much earlier when the camera industry started to go south.
With all that, I would like to remind you that our own [NR] forum is still alive and kicking. To keep spammers out, the forum is by invitation only (contact me if you want to create an account).
