why can't I send a imsg?According to the website I don't have the acces to send an imsg.Why?

How do pro players..ehm survive?I mean, talking about europe the 125 fps cup gives you 900-1000$ every month..if you get first ofcourse, and there is quakecon and dreamhack, but I don't know if 2 big lan events a year are enough.Players like evil/cypher might be able to live only with quake, but what about the other players?Those who are good, but usually don't get to the finals/win?
