ShareEverytime you sign on to something on the internet, you will receive a couple of captcha's. The real purpose? To identify if you are human enough. For god's sake, do monkey's use the PC?
The worst part is that some are so difficult that you'll have to squint your eyes and read it.
Hey! I am a Captcha. Since you have "loads" of time, i'll just take some more of it :P
