// @name            RealSimple - Printer Friendly Redirect
// @namespace       http://blog.monstuff.com/archives/cat_greasemonkey.html
// @description     Show the printer-friendly version of all articles on realsimple.com, even if you are not a registered user.
// @include         http://realsimple.com/*
// @include         http://www.realsimple.com/*
// ==/UserScript==

// The security of the registration check on realsimple.com is weak.
// If you turn javascript off, the page is displayed (no registration 
//  check) with no article (since it's loaded using javascript). But
//  it still lets you get to the printer-friendly url.
// If you grab that printer-friendly url, you can display the content 
//  of the article even with javascript turned on.
//
// This script simple snatches the printer-friendly url before the
// registration check javascript has executed, and redirects your browser
// to that url.
