The Internet has some unscrupulous characters who have written programs called "Spam Spiders". These programs travel the Internet in search of email addresses. They gather addresses and compile them into mailing lists which are used to send unsolicited email (affectionately called Spam). This site automatically changes the format of email addresses before they are displayed. By changing the format of the addresses, it becomes much more difficult for programs to harvest addresses while human users can easily discern what the addresses really are. This helps to protect you from unsolicited emails.
