I do the screen print thing that I recently learned . Alt+PrintScreen, then I paste it to paint and capture the face. Then imageshack it on here.
How do u capture it? and imageshack sorry i have no idea about any image related stuff.
To capture the image - press the Alt button on your keyboard and at the same time press the PrintScreen button (somewhere between your Delete button and your number pad on the right, usually).
Just after you do that, open Paint and click on File/Paste. Size it down using the crop feature, then save it as a .jpg file with File/Save As to your desktop.
Then go to http://imageshack.us/ and upload the image to ImageShack. They'll give you a series of codes to use - select the last one, and come back here. Open up a reply to this thread, then hit the Img button once, paste the code ImageShack gave you, then hit Img again, then hit submit.
NOTE - I'm a Mac user, and all that stuff about Paint was from memory. If I'm wrong, please correct me any PC users out there.
