When I play in a tournament other tournament players win or lose games. I would like to get an alert when some game in my tournament has ended. Like:" Mister A won from mister B in tournament C' . then it's more fun to follow the tournament players.
I know, when you enter 30 tournaments and each tournament have 100 participants then you will become insane from all the alerts so it should be optional.

I enjoy following the other games in my tournaments, but I don't think I'd like to stuff up my alert box with such trivial notifications. If I want to follow games, I just go to the tournament and click on "Games" so I can see all the current and completed games. I really don't think it's that much trouble.
