Is it possible to watch a section ? basically once a new thread is made or bumped you will see it when you click "Show new replies to your posts" ?
Because I'am clicking "notify" and I'am guessing that this should do the job however it's not .. ?
Yes. No, not to your "Show new replies to your posts", but to your "Watchlist".
Watchlist -> Watch board -> enter id -> click Watch board.
Every new thread in that section will be added to your watchlist. You find the ID, opening that section and looking at the address bar.
E.g. meta is 24
