// @namespace       http://www.jonasjohn.de/
// @description     The problem: You want to link to somebody's pages all tagged with "xyz"? But, because stumbleupon.com uses some tricky JavaScript, Ajax, ... techniques you can't simply copy the location in your browser... thats the point why I made this script, it simply adds a small "copy url" button to each profile. Very simple, but it helps :-)
