IETester: Test Rendering in Multiple Versions of Internet Explorer

IETester is an absolute life-saver. I wish I had found it months ago. With this amazing piece of software a web developer can see how his page will look in IE 5.5, 6, 7, and 8.1 all on the same computer. Since every version of Internet Explorer has its own quirks and it's impossible to install more than one version on machine, it can be very difficult to design a website that looks decent in every version. BrowserShots is a very handy system, but it's a pain to wait 5 minutes to several hours for a screenshot of your site to be taken. With IETester, you can test your site on your own machine in just a few seconds. Amazing.
