The system is not working properly. I am subscribed to my thread (mixed light runts) and used to be notified every time I updated. Not any longer. Which probably means anyone subscribed does not get notified either.
Thread tools caldwell^^, also OP if you post on the thread and no one posts then it wont show up in thread suscriptions.
Are you talking about email notification or a regular subscription? I'm not sure about emails but I know with a regular subscriptions, a thread won't appear as having new posts in your User CP unless there are actually new posts you haven't seen. Like skunky said, your own post will not cause a notification because you've already seen that post and it's not "new" to you.
