Disable the default "Categories" taxonomy in WordPress.
WordPress ships with two default taxonomies - Categories and Tags.
Admins who wish to use specific custom taxonomies may wish to disable these, to force users to use appropriate taxonomies only.
This plugin runs register_taxonomy('category', array()); during the init action.
This plugin sumply plugin-ises standard WordPress code circulating online - in this specific case, that posted by @Marc to StackExchange.
