CONCEPT Version .14

This page is the central location for CONCEPT Developers. Version .14(Read Version "point one four ") of the model was released on February 23rd. This is the final product of the first round of contractor activity. We are still early in CONCEPT's Development cycle and so we expect there will be new enhancements and patches often. We will try and keep the latest version available on this website.

If you have questions or comments about the beta test do not hesitate to use the Developers listserve. It will be the sole point of contact for model testers. The archive of the listserve can be found HERE. We have asked the contractors involved to focus their attention at the listserve so that any problems solved are transparent to the community.

If you have any non-technical questions about the model contact Mark Janssen: janssen@ladco.org
