I'm just come back from Microsoft Italy, after an entire (and full) day totally devoted to the new Navision 4 presentation for the Microsoft Partners.
It was a nice day, expecially because this was my first chance to meet all our NavLab Partners. As usual, Microsoft's events organization is great (and a great lunch too 
). The presentation has touched all Navision's aspects, from the new features, the new GUI, licensing and finally the new feedback center.
Regarding the feedback aspect, I've something to say... I come from the pure developer world and I can say that the MSDN Feedback Center is really good. If someone of us has a question or feedback to submit, we know where we've to go. What about MBS and Navision in particular?
There's not a good centralized feedback repository and a good Community for Navision at the moment. We've talked with the Microsoft Italy's feedback Center responsible and she said us that we can send her new features requests via email, she will collect the segnalation and will submit them to the developer Team. Really? I don't know if it's the right way to do... a well-done community must have immediate feedbacks.
