Myself and several others are in the process of launching a new site, Xmilk.com
Our goal is to build a forum/community around Home Media, including Windows media center, MythTV, MediaTomb, homebrew DVR, Upnp, etc.
We’ve also got a few people that are blogging here on these subjects.
Please take a look, check out the forums, the blogs, and help us build this community! If your interested in blogging on a Home Media subject there, let me know and we’ll get you setup.
