it's pretty nasty, to get in a room. if you have a slower net, you'll never come in.you can stay and stay clicking, but if theres a place free, and you click the room, you are waiting for minutes, and still its a open place. and after those minutes, it says it's full -__-. maybe it's a option to make more rooms for the same event like:
GM snipe event 1.1
GM Snipe event 1.2 or something
