First it was not adding the newest boards to the Classic version, and now you can't log on to Classic, So I'm on the New version whether I like it or not.

Progress and 'new" isn't always better!!

It is up and running now and I was able to log in, but for how long is anyone's guess. Frankly I am surprised that it wasn't disposed of months ago. You should use the beta version and get used to it. It will kind of grow on you once you get past the visual issues with the text.

How can I tell if I'm on the classic or new version?

Maybe it's my computer, who knows! sigh...
