Regrettably, it takes months to get used to the technical aspects of MESSAGE and to interpret the results correctly, and we do not feel comfortable in making the model easily available without having the resources to provide support.

MESSAGE is the subject of a special agreement between IIASA and the International Atomic Energy Agency (IAEA). IAEA distributes a modified version of MESSAGE with a graphical front-end as well as training on how to use it.
