I was sending some messages to a friend on MSN. He got angry and we had a fight. Now he never seems to be online/ replies to my messages. I wish to know if it is possible to know if he has blocked me, without asking him.

You can use a program called GAIM. It lets you log in to most chat facilities like MSN, YAHOO, AIM etc and also tells you exactly who all have blocked you.
