I'm talking about
Notify>Are you sure you wish to enable notification of new replies for this topic?
And yes I have
PROFILE>Notifications and Email>Receive reply notification only for the first unread reply.
Well as for me I normally receive notification from gambling discussion thread which I created since. But when I received the notification in the email, they normally warn me that if I did not view the link I would not receive notification from BTT again so for that I always view the comments from the notification link. That is the only notification that I am seeing. I did that thing when I was still a member rank. And now I have even forgotten the steps I used in setting the notification to my email. So I even need the steps again to do others.
Therefore, probably you are not receiving notifications because you are not following the instructions of the email. Because if you follow the instructions of the email I definitely believe that you must have receiving the notification in your email from all the threads you registered. So you can reset your notification or you can view the link from the email sent to you.
