Hey there viewon1 and JakeyBoy - you can create your own blog for free on lots of different sites. Microsoft hosts free blogs on Windows Live Spaces (http://spaces.live.com) and you can use Windows Live Writer to update your blog.
Wordpress is another great free blog hosting site: http://wordpress.org/
If you're asking about setting up a blog on Channel 10 - the site isn't open to the public but we'd love for you to ask questions and join in discussions here in the forums or via the comments section on each of the stories.
If you have ideas for stories or tips and tricks please let us know and if they're any good we'll feature them
Cheers -Fillo
