What is CAPTCHA and why do I have to enter it to post a comment?

Quick answer: Look at the picture (below) that contains letters. Type those letters in the CAPTCHA Code box.

Longer explanation: Our comment system now requires a CAPTCHA test (an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart" for all comments (unless you have registered and are logged-in). CAPTCHA is an image of letters that is dynamically generated (click the speaker icon to hear it or the arrows to load another test that may be easier to read). The letters, because they're part of an image and not text (e.g. text that you could cut and paste), are difficult for a spambot or other computer program to read. Yet, a person has little trouble reading the letters in a captcha image and then typing them into the form. Using a captcha test on our website is a great way to ensure, for instance, that a person and not a spambot is filling out a web form (we used to get 100 or so spam comments every day which our volunteers had to wade through). Also, a captcha can make it difficult for a person to continuously resubmit form information and overwhelm our comment function.
