Template:Tag
From Organic Design wiki
the purpose of this template is to perform the function of a tag that simultaneously registers a keyword as a category, and links to that category to list all pages containing the same tag. This is more manageable than adding individual 'see also' items to a page, as each related page will require the same additions to them, compounding maintenance. The tag category becomes a hub for related items, displays as one link, and eliminates the need for maintaining redundant lists of links in related items.
Usage
{{tag|keyword}} inline link
{{tag|keyword|}} hidden
{{tag|keyword|word}} pretty link (not implemented yet)
