Even now, when I start a thread, I get notified immediately. Only when I've replied to someone and they've asked more questions, I don't get notified. Also it's only an option and so no one will receive unsolicited emails.
Sometimes I find an interesting topic and would like to listen to that. There are so many forums and so many topics, with my normal searching, I may miss that. So, I would like to Add myself as a listener
so that I get notified when the topic develops and I don't miss the topic. This is just an idea. I understand it's a 3rd party software and we can't do much.
