It's 2006, and after a 3 year hiatus, the website is back up. For info on what's been done and why it's been down so long, see http://www.yellowstone-online.com/sitehistory.html and http://www.yellowstone-online.com/ytwelve.html
Things could still be spotty, but a lot of dead links have been fixed, and there's a little bit of new material.
