In my experience Double list has been terrible. Even when I upgraded from a free to paid subscription, I did not get more than a couple of replies. One time I sent myself a couple of replies, none of them reached me. I was on a paid subscription, and when I asked DL, they had a confusing reply to offer.

Now DL IS A TOTALLY PAID SITE. That means one cannot post, or read posts reply or get replies without paying for a subscription. Good riddance, and maybe the ?Beginnning of the end? for this lousy site.
