Bleh

Sigh. Human, it's not that hard to understand. You have replied to this thread. This automatically watches this thread (similarly, when you edit a talk page, it's automatically added to your watchlist - I haven't tested, but lqt probably respects the preference option). If you don't want that, go to preferences->Watchlist, and untick "Watch threads that I create or reply to". Also unwatch this page if you are watching it and any individual threads on it. When someone replies to a thread you are watching, it will count as a "new message for you". Yes, the phrasing is stupid, it should be "there are replies to threads you are watching". You have to click Mark as read on Special:Newmessages to clear the notification.
