S2 in in alpha at the moment, this means features and functions are still being added. Once that's complete it will go beta, that means all features and functions are added and any remaining bugs are being worked on. Once all the bugs are worked out it goes final.
The server is 'Auto Success Ballast Server' which was created to automate the weekly 'home' games between a group of friends. The server is online 24x7 for anyone to race on.
