Well, not only am I sure this will be exploited, I am not sure this is valid or honest. NOTICE!! On the Microsoft4me site, it says that this is specifically a Software Design promotion, but then it says you can participate in any of the contests...anyone think that's a bit strange?
However, a whois lookup for Microsoft4me, shows that the site and it's content is registers to Microsoft Corp.
BUT!! Most important information. ANYONE can enter the Algorithim contest RIGHT NOW! Just move the robot so you get some points then upload it. It takes mere minutes. Then, we'll see if we get our games. No waiting to take a quiz. I figured SOMEONE on this thread would figure out the one contest that can be done instantly, but it seems everyone would rather wait a week then get up at 2am????
