What is the "security code" on the contact form

The security code is actually a CAPTCHA, which is a safeguard that protects this website against automated internet programs (called "bots") from generating thousands of malicious self-proplled e-mails to our site. Every time a user enters our contact page, a new, unique four-character CAPTCHA (or security code) is generated. Humans simply have to read this code and enter it into the appropriate field to pass. But current bots cannot. This ensures that your web message is delivered to us quickly and efficiently so we can get back to you as soon as possible.
