Here's a nice and comfortable way to check Seven Forums using Windows Media Center.
First, download and install Media Center RSS Reader: http://vistamcrssreader.oabsoftware.nl/
After installation, RSS Reader appears in you WMC Extras. It can read and show all IE RSS feeds, no support for other browsers.
Open your IE, go to http://www.sevenforums.com/external.php?type=RSS2
and subscribe the feed.
Open WMC, go to extras and click RSS reader. You are done.
Im posting this from WMC. Only difference compared to using a browser is that you can not use attachments when posting, so the screenshots here are added later from browser. Also cut / copy / paste work only using keyboard shortcuts, WMC does not show context menus.
