I just tried to access alt.hi-po.big-block-ford-mercury through Google Groups and it's not there. You can do an Advanced Search and access archived threads. But even those archived threads are missing the link to the NG window itself, what you might call the "home page," that displays threads by subject line. (Those who never use Google Groups probably have no idea what I'm trying to describe here.)
Did Google drop the NG, or does it not exist anymore?
