There are four types of links in MediaWiki:
To add an internal link, enclose the name of the page you want to link to in double square brackets. When you save the page, you'll see the new link pointing to your page. If the page exists already, it is displayed in blue, empty pages are displayed in red. Selflinks to the current page are not transformed in URLs but displayed in bold.
The first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link will have a similar effect as typing a space, but is not recommended, since the underscore will also be shown in the text).

External link, different title |
[http://mediawiki.org MediaWiki] | MediaWiki |

Category link | [[:Category:Help]] | Category:Help |
Link to an article in a different language ("Main Page" in German) | [[:de:Hauptseite]] | de:Hauptseite |
Internal link to image file | [[media:example.jpg]] | media:example.jpg |
Internal link to pdf file | [[media:example.pdf]] | media:example.pdf |
Interproject link | [[wiktionary:example]] | wiktionary:example |
mailto link | [mailto:info@example.org email me] | email me |
redirect | #REDIRECT [[Main Page]] | → Main Page |
External link to video file (.avi, .mpg) | [http://en.wikipedia.org/wiki/.avi .avi] | .avi |
External link to sound file (.mp3, .ogg, .wav) | [http://en.wikipedia.org/wiki/.wav .wav] | .wav |
External link to a document (.doc, .pdf) | [http://en.wikipedia.org/wiki/.doc .doc] | .doc |
Description | You type | You get |
Piped link, different title |
[[Main Page|<span title="different title">different text</span>]] | different text |
External link, same host unnamed |
[http://((SERVERNAME))/pagename] | [2] |
External link, other host, pass pagename |
[http://google.com/search?q=((PAGENAME))] | [3] |
Google link, pass pagename | [[google:((PAGENAME))|Google "((PAGENAME))"]] | Google "Link" |
mailto named with subject line and body | [mailto:info@example.org?Subject=URL%20Encoded%20Subject&body=Body%20Text info] | info |
By default, when you write a URL as is, it will be transformed to an external link.
To avoid that effect, put the URL between <nowiki> start & end tags as in:
<nowiki>http://mediawiki.org</nowiki>
Interwiki links are links from the local wiki to another wiki. For example you can link to the Sunflower article on wikipedia.org by typing [[w:Sunflower]]. This results in a link like this: w:Sunflower
Similar to internal page links, you can create piped links, with alternate link text. e.g. [[w:Sunflower|big yellow flower]]
Basically this is an abbreviation for longer URLs. A very similar link could be created as a normal external link by typing [http://en.wikipedia.org/wiki/Sunflower Sunflower], but interwiki links allow you to type out an easy and compact link, almost as if you are linking to a page on your own wiki.
