Redirect to:

This page is a redirect. The following categories are used to track and monitor this redirect:

With possibilities: This is a redirect from a title that potentially could be expanded into a new article or other type of associated page such as a new template. The topic described by this title may be more detailed than is currently provided on the target page or in a section of that page.
- When the target page becomes too large, or for any reason a new page would be an improvement, this redirect may be replaced with an article, template or other project page that is carved out of the target page. See also {{R to section}} and use together with this rcat when appropriate.
- If the topic of the redirect is not susceptible to expansion, then use other rcats such as {{R to section}} or {{R to list entry}} when appropriate.
- Since a new page may be created, links to this redirect should not be replaced with a direct link to the target page. To make redirects to this page, use {{R avoided double redirect}}.
- {{R printworthy}} should be used together with this template when applied to a redirect in mainspace.
- When used on a template redirect, it will automatically populate Category:Template redirects with possibilities.

From a list topic: This is a redirect from the topic of a list to the equivalent list. It is not necessary to replace links to this redirect with a piped link to the target page.
- For redirects to a specific entry in a list use {{R to list entry}} instead.
- If the redirect topic is detailed enough to sustain its own article, then use {{R with possibilities}} in addition. If notability of the subject can be shown, then be bold and convert this redirect into an article on the topic.

When appropriate, protection levels are automatically sensed, described and categorized.
