It's nothing fancy, but the search works like a charm. The best part is that it was truly simple to install, and the directions were the first I have encountered that were cogently written and thorough enough for a novice. I've downloaded and used several more from this source with the same experience.

Like so many scripts in this list, you can forget carraige returns that allow input in paragraphs without submitting, reloading and resubmitting. Worse yet, none of the security features of this script work, and the control panel is useless--profanity gets right through and you can forget maintaining both the bad words list and the banned IP list. This is definitely not a script you would want to run on a site accessible to children.
