There is a new Discussion Group available from Autodesk. It's name is "Civil 3D Wishes". You can find a link in the left hand column of this blog or you can use a news reader and point to "autodesk.civil3d.wishes".
As the name implies we can post our wishes for Civil 3D. They are asking for input, and Autodesk says that Product Management, Product Design, Development, and Testing will be watching. I hope it is well used and listened to.
