Maybe I misunderstand your meaning regarding personal and business notebooks, because I can see a very clear demarcation within my EN. For me this is one of the great successes of EN, providing business users with a private personal section which helps to integrate them into EN life. Don't get me wrong there are still many features which I perceive as essential for business which are not currently available in EN. However my business is small enough to adapt for now whilst EN evolves. Of course the basic features for project control have to be there, and the principal of sharing is one of these. We now have suppliers and customers contributing to projects with direct input into EN, including uploading large files. Yes I have a wish list for improvements, like the ability to make a notes private so only company employees can see, but maybe this will happen one day.
