// @description   Due to a stupid off-by-one error, discussions sometimes present you with a blank page.  This goes back one page when it happens.
// @include       http://*.myspace.com/*
// ==/UserScript==

// If the page has text of the form "Listing 16-16 off 16"
if (document.body.innerHTML.match(/Listing\s(\d+)-\1\sof\s\1/)) {
	// Find the page number in the URL
	pagenumber = window.location.toString().match(/page\=(\d+)/)[1]
	// Go back one page
	window.location.href = window.location.href.replace("&page=" + pagenumber, "&page=" + (pagenumber - 1))
