Ryan has updated all of the geekdojo blogs with a few anti-spam measures.  You will notice the captcha image at the bottom of the comment form.  You need to type in what is displayed in the image in order for the comment to post.  It’s a pain yeah, but thats what happens when a few freaks ruin the Internet for everyone. 

If you mis-type the captcha text, your comment will not post, so be sure to check.  I may take a look at the control he is using.  I am interested to see if there is a way to better integrate it or at least validate the text before posting.
