Spam Filtering

A new spam filter has been added to this site.  If you have Javascript enabled, you should see no change in the behaviour when leaving comments.  If it is shut off, you will get a challenge to do something to prove you are human, not a robot.

Please note that not all comments that people leave are approved for visibility by everyone else.  I keep them all, and some become ideas for future threads.  If you think that you have left a truly cogent comment and I have missed it, please send me an email (using the Webmaster link at the bottom of the page) so that we can figure out where your comment is going.

With luck, this change will eliminate the need for me to wade through piles of messages flagged as spam looking for the one or two that are from real people, but which triggered the old filter based on content.
