Just a note to anyone interested in my Category Access and Category Order plugins... I'm ceasing development and support. A few reasons: (1) WordPress doesn't have a good API, which forces me to update it with every release. (2) WordPress is riddled with security holes, forcing me to update every other week. (3) I find it easier to "outsource" the infrastructure for keeping up to date with family through Facebook.
The code will remain available at http://www.coppit.org/code/index.php in case others want to pick up the torch and carry it forward. There are also supported alternatives out there. If you use or enhance my code please honor the license.
