OpenDNS: When your browser can't find the website
Last spring, we outgrew once and for all the capabilities of our current server (i.e., computer setup) situation for our website customers. So we had to move everything to a new server. On most counts, this was a good move. The new server has more space, it's much faster and should all around work better. However, we ran into a situation that is becomming a problem for websites all around.
CAPTCHA stands for Completely Automated Public Turing test to tell Computers and Humans Apart. For the non-computer scientists in the audience, that may beg the question, but the bottom line is that it is a mechanism to hopefully limit the amount of spam we get from our contact and other web forms.
