Corporate users can subscribe (at no extra cost) to model composite emails (1-5, 6-10, 11-15 day anomaly maps) as well as ENSO/SST updates, weighted degree day forecasts from the models, teleconnections, precipitation forecasts, and even NAM wind output.  To get there, go to My Account in upper right.  Then Edit Profile.  Click on Edit again right below your username.  Scroll down list to Email Subscriptions and check the ones you want (if you do not subscribe to the midday model predictor, you will not be able to choose those options).  You can change these settings whenever you want.
