I just noticed that it was a PM - My bad. There is a similar ! triangle at the bottom of incoming PM's too.
At the bottom of the window that the post is in there is a triangle with a ! in it on the left side. You click that to report stuff like this. Not sure who gets those messages. Maybe clicking on it sends high voltage to the keyboard of the person who posted the message. I like to imagine that when I "report" posts.
On a related topic, will the price of AFM be going down significantly now that you have experienced this financial windfall?
