I have created a 'sim', 24/7 available, for tests of scripts. You can access it by hypergrid or using the user: "Guest One", pw:"123456". Accessing by hypergrid you can copy the objects having the scripts. The address is: http://126.96.36.199:9000.
Let me know if you are having any problem. My comm line has only 256 kbps... There are a "vehicle" that you can drive! I am using the last "diva version". Enjoy.
