Just a quick note about a nice installer for running multiple versions of Internet Explorer (standalone). You can snag Multiple_IEs here. To be completely honest, this really isn’t a necessity beyond IE6 (because of the massive install base), so you can run it side by side with IE7.
Very useful to make a note of… someday I am sure I will need to care, right now just isn’t one of them
