Hey thanks for the effort of creating a bookmarklet for ColrGrabr. I will provide it directly on the page.

Btw. you don't need the ?url= query param.

  javascript:(function(){var%20s=encodeURIComponent(window.location.href.match(/:\/\/(.[^/]+)/)[1]);open('http://colrgrabr.swissamigos.com/#+s);})();
