I've just released an HTPC site that is intended to be a community managed site. Users can share their HTPC software, rate and review it; post guides for help the public; communicate on the forums and stay up to date with the latest in HTPC news.
Please check it out, sign up and help create a community.
You can find the site at: http://www.htpcresource.com/
Looking forward to meeting you all.
