Cool K-12 LMS

While researching for my webliography I came across an interesting site that is geared towards the K-12 audience. Over that past few years working on the IT degree at Bloomsburg I have come across a lot of great resources. Yet, many of these resources are geared towards older audiences, that is why I was very excited when I came across this site. Basically it is an LMS that allows K-12 teachers to create lessons for their class and then assign them to the entire class or specific students. This way students log in and must complete the correct assignments and tests. Visit the site at http://www.alpha-lms.co.uk/ and let me know what you think about it. Also please share if you have any experience with this software.
