And how? Google was disallowing group replies to posts more than some months old... even in this thread, I see it only allowing group replies to yours and his. I see from his headers he's using google... ohhhhh, the new google groups doesn't make that age distinction. I wish there was some way to tell them that is stupid. I've submitted under the "why you are switching back to the old google groups," but that's kind of like posting that Oracle should keep supporting hp-ux.

At least Howard's explanation is still the best on the subject.
