After the protest note, I followed up the matter with a phone and the matter has now been clarified.
The Media Council had two sets of advertisements. One that was in the papers and also on their home page captured all the other categories except the culture and the arts on (MEDIA AWARDS ADVERT MEDIA AWARDS ADVERT). Then there is one in their download segment that has the category (Media Awards Entry Form FEBRUARY 2013).
It looks like the arts have been incorporated after all. Many thanks to Victor Bwire. The awards are open to journalists accredited by the Council.
