Lauren,
I will begin looking this weekend at how to do this via straight Javascript. The reason I am looking at that approach is that I was listening to a podcast this morning on the way to work and heard that Google is locking down extensions to Chrome to just those extensions that appear in the Chrome Web Store so if you install an extension such as Kango/Greasemonkey/etc that you download from SourceForge or the like Chrome will begin to ignore them since they cannot find the libraries in the Chrome Web Store. Given the security approaches the browser developers are beginning to take (and dynamically changing a URL after the click probably would be considered a hack by the security folk) this might become more difficult if not impossible to do with an extension. I will do more investigation this weekend.
Mike
