It's a Javascript trick that is active on this wiki. For example the HTML code  will automatically replace "Name" with the name of the user who views it (but remain unchanged for anons). Try it out!

I added this long ago to prank other users, and nowadays most of the active wiki users have picked it up for their profile pages or signatures.
