Actually I was looking for a way to remove threads completely from refreshing to the top of the pile (there are some games and other VERY active threads) under MY POSTS.
But... now, thanks to some replies, I have found a way to kind of by pass looking there for new posts. As an eg. I don't want to play 'why the last poster must be banned',or read about the last lava tank sale, or so-and-so's box mod etc. etc. Also, one Provari is more than enough for me. (And just because I posted once or 10X in a thread, doesn't necessarily mean I want to read about if for ever and ever - till death do us part!).
How about going to the bothersome thread, and then selecting UNSUBSCRIBE under THREAD TOOLS? I've never seen these POP-UPS, I wonder if there is a setting in your account settings to get rid of them??
