The developers of 3dMax started a great system a few years ago to determine what users want most in the way of new features, bug fixes, UI changes etc. They called it the User Voice. Participation is easy. There is room for discussion and clarification. The most wanted ideas quickly, and clearly, rise to the top. Voting is limited in a clever way and forces users to choose their most valued features.

The general rules, copied from: http://3dsmaxfeedback.autodesk.com/forums/80695-general-feature-req...

• Each user has 20 votes for each forum
• Each idea can have no more than 3 votes by a single user
• If you enter an idea, it will cost you 1 vote – therefore try to make sure the idea doesn’t already exist
• The more precise and detailed a description you give, the more likely your idea will be considered
• When an idea is implemented (or declined), votes are returned to all the users that voted
• Users can change their votes at any time
• Admins can move, edit and delete ideas as they see fit to better meet the goals of the forum
• We will flag ideas that are getting our attention as “under review”. Because of limits on what we can say publicly, that is as far as we can go with commenting on a particular idea. If it is “under review” it simply means we’re studying it for possible implementation or gathering data, but there is no commitment to do it.
