A month ago, Wikia announced a parent filter that could be installed on entertainment wikis such as ours.

http://metalheroes.wikia.com/wiki/MediaWiki:ParentFilter
Despite the name, its function is to inform parents of the content in a certain franchise in a short summary rather that scour the entire wiki to learn about it. Giving it ratings, stating the content in the media in question (sex, violence, drug use, profanity etc.) and labeling the media by category. (video games, movies, TV, comics)

I made inquiries as to how it works and if a custom template can be made for our wikis so we can use it to inform parents of budding otaku as to what their kids are into.
The administrative staff can chime in their questions and thoughts on it in the above link and you can discuss below.
