Index to all categories on this Wiki.
To get a list of all categories on this Wiki, click on the title at the top of this page.
To create a new category, create a new page called "Category Topic". Add your category to the list of all categories, and any sub-categories. Order categories most-specific to least-specific:
<<categories>> Sub Topic | Category
Which will be rendered similar to:
!!!!!! | [Category Sub Topic] | [Category Category] | !!!!!!
Add pages to your new category by linking to Category Topic at the bottom of the page, using the <<categories>> format as shown above.
DKF: Note that if there was no page “Category Sub Topic” but there was a page “Sub Topic”, the above <<categories>> line would result in that page being linked to; the Wiki prefers categories to start with “Category” but does not insist on it (and a number of large categories in fact do not).
Tips:
It would also be appreciated if you would add an entry at How do Wiki Categories work describing what kinds of things should be tagged with your category. For example, the category of personal Wiki home pages is called Category Home Page. To add a person's Wiki home page to the category, place a link to [Category Home Page] on his home page.
See: http://emacswiki.org/ for a good example of how to use categories.

Lars H, 2009-02-03: One thing the anonymous "wikigardener" seems to have missed is that categories generally don't fall into a strict hierarchical scheme (as the new text above would suggest), but more often end up being related to each other. Traditionally such related-to links have been found as bulleted lists under a heading such as See also, whereas only the category-hierarchical links have been put in the category footer.
EMJ 2009-02-10: Agreed. The good thing about categories is that they are not hierarchical, a page can be in several categories, and may reference other categories within the body of the page, either in a list or inline in the text. Also, there is no "list of all categories" except the one generated automatically by clicking on the title of this page. I think the partial list on How do Wiki Categories work is only justified as a reference to help decide what categories are appropriate when it is not obvious from the category name. And I don't think there is any right order for the categories at the bottom of a page - alphabetical might be a sensible choice, but I think it depends. ...
