It was all over the news a while back. Microsoft announced that a new service would provide small businesses a number of hosted service that included a web site (complete with your own domain name), e-mail accounts and web applications to help with everyday tasks like collaboration between employees, project management and customer communications.
I looked at it a while back, but the only thing we could do at the time was to sign up and wait. Well, now the service is available in beta form. I applied for a free account and got set up with my own domain and everything. Very nice… There are some restrictions, though, like the fact that the service is only for US residents.
