Suggestion, nix Category bindings – implementation of RnU

I think this plugin is great for compliance use where you can take a bunch of people and make them sign off acknowledgement of important announcements and what not. But I feel like binding to the category is too restrictive. This creates a situation where you have to consciously think about the organization of your categories in order to use this plugin. It becomes more troublesome when wanting to use it on multiple parent categories.

I would actually think it would be a great idea to instead use either a shortcode, (something like [rnu_ack]) in the post body, OR to have a checkbox available on the post editor page to toggle RnU on/off on a per-post basis.
