UPDATE 02.21.2010:  Michael's post was updated to include a minor tweak required for BlogEngine 1.6 support.

I’ve gotten a fair amount of attention regarding a post which details ways to reduce SPAM within your BlogEngine installation.  Yesterday, I received a comment from Michael Ceranski about a his adaptation of a CAPTCHA implementation. 

I’ve installed it here, and it seems to work quite nicely.  A well-done and seamless integration within the AJAX commenting system BlogEngine employs.

Nicely done, and THANKS!
