I've been a big fan of Boxxet since late March when I got my beta invite and started banging around the site. In the last few months You Mon Tsang and his team have been making dramatic improvements to the user experience, the back-end server, the AI and most of all, the quality of the Boxxets (pron. "Box Sets").
I've been getting a number of comments lately from folks looking for a beta invite, of which I still have a number. If you want one you need to email me - leaving an anonymous comment doesn't give me a way to get you the invite. Thanks.
