KB Support includes an option for you to restrict access to each KB Article you publish.
If an article is restricted, any user attempting to view the article must be logged in to your website. If they are not, they will only see the article excerpt followed by a notice. The remainder of the content, including comments, will not be visible until the user has successfully logged in.
Template tags are placeholder text that get replaced during processing of content with information that is relevant to the ticket that is being referred to.
KB Support has a number of built-in template tags that can be used within ticket notifications that are sent during ticket creation, reply and closure as well as within the template pages that display content on the front end of your website.
