sorry if this sound noob, im just new here, just want to know, how to bookmark a thread..thanks
On the upper right hand corner of this page, in the same line as the Title of the thread , you'll see a "Heart and + " icon. All you have to do is click on it and you've got this or which ever thread you were on Bookmarked...
every time i visit a thread, i don't see a heart+ instead there is a delete flag
That's because you've already been to the thread before, so it's flagged, and any updates on that thread show up in the right hand column. If you want to bookmark a thread that you have already visited then you'll need to go to the main thread console of the forum find the thread and bookmark it from there.
