With either of the current Web based UI options, the ones that are not brown/orange. Choose RACE then the Black section labled Competition System. There you will see several series of races that qualify or run about every 5hrs, depending upon your location they may or may not be convenient. This is a beta process that will become the default online system once it is fully fleshed out. Otherwise, I don't think there are any official S397 servers online any longer. It's all gonna be tied to the new comp system inside the new UI.
