Help:Link

Here's how to add links:

Internal
To add a link to an internal page (in the wiki), use these link styles:
 * For an article page: This one normal page
 * For a page in another namespace: Namespace:Page name
 * However, links to images and categories (without using the image on the page, or adding the page to the category) must be linked like this: File:Image name or Category:Category name

Interwiki
To link to a common external page, like Wikipedia, use a namespace-style link with one of the interwiki prefixes: Gamer

External
To link externally (outside the wiki), use one bracket pair instead of two, as well as an absolute path: To link to someone's email, use the mailto: prefix: [mailto:joe_person@email.com] To create an external link without the arrow symbol, use plain link like this:

Appearances
To change the appearance of an internal or interwiki link, use the vertical bar symbol (or "pipe"): This neat page To change the appearance of an external link or an email link, insert a space after the link: A neat site In an link with a namespace (or an interwiki link), the prefix is removable with the pipe (|) symbol: Main Page In a link with trailing parentheses (), the parentheses, as well as the words inside them, are removable with the pipe (|) symbol: The Legend of Zelda (video game) In a page with trailing parentheses ('), and if a page that also' has trailing parentheses is to be linked to, one may use the following trick: |The Legend of Zelda Note: The page linked to must contain the same word as the page that got the link placed on has. For example, the above link would link to the "The Legend of Zelda (series)" page if, and only if the page the link was put on also contained the word "series" in trailing parentheses.

Link colors

 * If you see a deep blue link, it means it's a link within this wiki.
 * If you see a light blue link, it means it's an interwiki link.
 * If you see a red link, it means it's not a real wiki page, or it's not a correctly typed link.

Link symbols
Figuring out what the symbols next to some links mean. If you are using Internet Explorer or Opera, you may not be able to see the following symbols.
 * If you see a light blue link with an arrow next to it, it means it's an external link.
 * If you see a [mailto:joe_person@email.com light blue] link with an envelope next to it, it means it's a link to someone's email address.
 * If you see a light blue link with a chat sign next to it, it means it's a link to an irc chat.
 * If you see a light blue link with a lock sign next to it, it means it's a link to a secure page.
