My name is Zach Dennison, and I joined Wikipedia on May 12, 2005. I am always using Wikipedia as a resource, yet I am fairly inactive when it comes to editing and creating articles. My biggest interest is in computers. I can write batch, HTML, and PHP files, and I can write in wiki markup. Most of my article contributions are to correct typos or add a small amount of content to an article.
You know normal links—they look [[like this]]. But did you know that you can use normal links to pages on any other wiki? This is called InterWiki linking, and applies to all wikis, not just Wikipedia's sister projects. You can link to a page on MeatballWiki by typing [[MeatBall:PageName]], for example. See Interwiki map.
However, links to Wikipedias in other languages are done a little differently. You can link to these by typing, for example, [[:de:Hauptseite]] (replace "de" with language prefix). The colon at the beginning prevents the link from becoming an interlanguage link, which shows up in the left sidebar.
To hide the prefix from the link, use the pipe trick.
Bonus tip: the same basic syntax works in the search box. (Try typing in Meatball:)
