Since it's first release EwE has been a free software and is developed on a non-profit basis. This will continue to be so. However, if you foresee that you need scientific or technical help when using the software please consider taking out a user support contract. Such a contract allows Ecopath Research and Development Consortium developers and scientists to dedicate time and effort to address your questions, solve issues that you discover and implement features that you may desire.

For more information please read our support section, and contact us by email to sign up.
