"Last night I added a new preventive measure for comment spam at this site.  Its a very simple image security access code, that is required before submitting a comment.  I tried to stay away from using this as a preventive measure, but the comment spammers are just too much to deal with.  I apologize for any inconvenience when commenting...All you need to do is type in the code, into the box provided and then click submit.  It should go through just fine.  Any comments, feel free. :)"^^<http://www.w3.org/2001/XMLSchema#string>
