I signed up for the beta in, oh, June 2007. Then in July 2008 I get an email stating they had joined up with Codemasters and I would have to sign up again for the beta at the new, updated and improved website. I did so. Then a few months ago I got ANOTHER email saying, yet again, I would have to sign up for the beta. Again.
I didn't, because at this point I no longer believe the beta exists, and no longer care to be in it.
