Click forum in the nav bar to the left. The forum there has been down all day, but it is usually back after a day or two.
I use Fraps if I need a specific screenshot from a replay. But FSScreen (@ Nuno's site) is also worth using.
Alternately, and if you have about 100 megs of free space, try having Hypersnap running in a game with only the AI, and the camera set to director mode. Keep taking screenshots until you have about 50 or so. At least 5 of them are gonna be very good to great. Thats how I get pics for my desktop.
It's only after we've lost everything, that we are free to do anything.
