Apparently [mod\_security is really aggressive around certain words](http://www.shamusyoung.com/twentysidedtale/?p=802&ref=chrismessina.me) (like in [my previous post](http://factoryjoe.com/blog/2007/01/25/technology-for-the-future-macfuse/?ref=chrismessina.me)). To get around this, [add SecFilterEngine off to your .htaccess file](http://www.shamusyoung.com/twentysidedtale/?p=802&ref=chrismessina.me#comment-27084). You might not want to leave that snippet in there long, since it disables the security check, but if you find WordPress [denying you the ability to post](http://wordpress.org/support/topic/41629?ref=chrismessina.me), it's worth a shot.
