This will allow users to hide media content they prefer not to see on various pages and widgets. This only works for "Media". It could work for "Resources" as well but it would require tripling to resource categories which would be way too unwieldy. By default, all media content is viewable to guests and these hide options are unchecked by default. I have also fixed "What's new" to now include all categories as the user pref will dictate what they actually see there. This site is meant to be open to all so the public view and user preferences reflect that. If you think we need "Hide General" I could add that as well. 
Lastly - I added SFW/Artistic media categories as suggested.
