GAOTDis offering a free screen cap tool today. There are 2 things about this one that makes is different from most screencap programs. 1st: It will capture text as text, instead of as an image. 2nd: It will capture the text behind the asterisks in stored password boxes. Which might be useful to some members on shared pcs. If you can get it to install on a stick even better (not sure about that though as I haven't tried the proggy yet.)
You must download and install it today, as it's only free for today. Be sure to check the readme in the download for any install instructions or registration passwords.
