Whenever we are viewing a thread,we sometimes don't agree with what the other users are saying so we press the REPLY or the QUOTE other user's response to give our own opinion but the other person doesn't know that we replied or quoted on their post.
The other user will have look through all post's in that thread to find out whether somebody didn't agree with him.
If nobody quotes or replies to our post and post normally in the last box at the end of the thread then no alerts and things should run the way they are.
But if anybody does then we should get Alerts like message alerts,wall post alerts,etc whenever somebody replies or quotes our answer so that we can reply to him on his opinion.
