Fencer: So, I assume this Event box is for those people who found that sort of message annoying. So, will they delete themselves after a certain amount of time? Or after the # in the box reaches a certain point?

I personally don't care, because I'm one of the weirdos who reads all those messages. (Usually because I like to click on my graph and remind my self how I'm doing, and that sort of thing). But for those who don't like the messages anyway, it seems at first glance that it's just a separate box that will get a gradually higher red number after it.
SO, I'm just curious.
