I've finally put up a CAPTCHA test for comment posting. This should reduce the amount of comment spam we've been getting. All the credit goes to Davide Mauri for creating a detailed list of instructions for implementing this in .TEXT. You can find the details on his other blog. Previously I had restricted comments on posts older than 30 days. I've removed that restriction. Please let me know if there are any problems or if something doesn't look quite right.
I want to add that this uses a great HIP control
