website-name colon text makes the wiki look up website-name in a list, fetch the corresponding URL, tack text on the end and produce a link to the result. This is called an /InterWiki link. website-name is case-sensitive.
if you write this immediately before a colon, and a wiki page name immediately after, the script will produce a link to that page on the wiki, like this: Click me, I do nice things!. Sometimes, the wiki will display square brackets around the link if it thinks the label text used for the link might mislead people.
NIV
produces link to a bible passage (New International Version, english). KJV goes to King James Version, YLT goes to Young's Literal Translation. [Other] versions/languages available on request.
Can we get the absolutely hilarious 'new youth' version?
If you can find (or write) somewhere that'll search it for passages that I can link to ;) - MoonShadow
