Implementing CAPTCHA. Easy AND fun.

It took less than an hour to implement captcha on my personal blog, based on the work of Chris Kunicki, BrainJar, and CMU nerds.  Details, links, and code excerpts on my personal blog here.

That's excellent, Richard. Thanks. Think I'll stay with the noisy grey and 3 numbers for now.

I’m amazed, I must say. Seldom do I encounter a blog that’s both equally educative and interesting, and let me tell you, you have hit the nail on the head. The problem is an issue that not enough men and women are speaking intelligently about. Now i'm very happy that I stumbled across this in my search for something regarding this.

Hi, I believe your website might be having web browser compatibility issues. Whenever I look at your website in Safari, it looks fine but when opening in Internet Explorer, it's got some overlapping issues. I just wanted to give you a quick heads up! Apart from that, excellent website!

Howdy! I know this is somewhat off topic but I was wondering if you knew where I could find a captcha plugin for my comment form? I’m using the same blog platform as yours and I’m having problems finding one? Thanks a lot!
