That's what it looks like from the screenshot. . .
But you probably have to pay for your own domain name. Nope just checked the website, domain is free, too.
But if you start to distribute larger files or your programs get very popular, you might have to think about paying for more storage or bandwidth. That's the only downside to it I can see. Oh, and it's Microsoft.
I'd also be cautious about whether or not you actually own the domain. You don't want to start an awesome website and have Microsoft steal it because you didn't read the terms of service.
