The 'Help' category and the 'How to articles' category
Originally when the help articles were created, the wiki did not have the "How to articles" template. Now that we have this template, the end users can more easily navigate to the help content, but only if this template is added to the page. Adding the template to a page that already has the Help category on the page may be confusing. As a result, I have several questions about the two high level categories related to help content in the wiki:
 * Is there any advantage to having both the "Help" category and the "How to articles" category?
 * Should both categories be added to all the help articles?
 * Or, should one category be used and the other one discarded?
 * How does someone know when the "Help" category is not needed on a page?
 * If a page already has the Help category, and then the "How to articles" template is added to the page, should the Help category be removed from the page?
