Don't know if this is a "clear your browser cache" issue, but here goes.
When I click my old bookmark for the old home page, I get a 404 page indicating a routing problem. If I click on the CH logo contained therein, it takes me back to the page with Jim's Big Announcement, with the "cut to the chow" link at the bottom. If I click on that link it takes me back to the 404 page. And so on. (Helpfully, the 404 page also has that link to User Help, so I'm still able to access the boards)
I know there's a homepage in there somewhere, from when I was looking at the Beta site. What do I need to do to get to it?
