After I read your post, I started checking the other "sister's" sites as well
Secretpennystocks is still redirecting to the APS site Pennystockgains is taking new sign ups Pennystockadvice is taking new sign ups Pennystocksexpert is taking new sign ups Pennystockuniverse is taking new sign ups Pennystocks123 is live but not taking sign ups
Just like with APS, if you sign-up, they give you the double opt-in email. But if you go to sign up again, they let you double opt-in again, and again. That is strange for an ESP not to check the database and tell you that you are subscribed.
