// This script replaces any given word or text fragment with
// whatever you want: new words and fragments, or even HTML!
//
// Actually it's pretty simple: add the words or fragments you
// wish to replace to the array "oldWords" (each word placed
// between double quotation marks, and separated by colons as you
// can see below) and add their replacements to the array "newWords",
// at the same position as the original words in "oldWords".
// The example is pretty self-explaining.
//
// The script is case sensitive, meaning that if you add "something"
// to "oldWords" array it will not recognize "SOMETHING", or "SoMetHInG".
//
// You can adjust the existing arrays in this code as you see fit,
// as long as both arrays keep the same size (same amount of words
// in both arrays), otherwise a script error will occur.
//
// Copy this entire code and paste in the webstats box at your
// Look and Feel page.

// You're free to use this script as long as this comment remains intact,
// and as long you won't use it to cripple the comments of your visitors;
// after all, no one likes his/her words getting twisted...
