ICRA labelling
My sites have always been ICRA labelled, and I recently moved over to their new RDF labelling system.
However, labelling means that you have to always make sure that all your pages fit in with their labels, and make new ones as the content changes. This is why I’ve now updated my labels for the writings section to inform people that some of the content there may not be suitable for all ages. I’ve also added alerts to all concerned pages, and appended their links with graphics to make sure that everybody is clear about their content.
