21	* ) );
22	*
23	* For maximum compatibility with different methods of posting users will
24	* designate a featured post tag to associate posts with. Since this tag now has
25	* special meaning beyond that of a normal tags, users will have the ability to
26	* hide it from the front-end of their site.
