This is the curve exchange. On the curve exchange forum users can request curves (aka media types) that someone may have already created. Also people can upload curves that they have created to share with others. The reason for the curve exchange to live here (as apposed to the community forum) is because many curves are PiezoDN and are not licensed for public release outside of the PiezoDN/Pro group of users.
