Flutterby™! : death of email

Charlene wants a dropdown menu for the revamp of the Delightfully Cherished site. I was using the technique from A List Apart: CSS Design: Taming Lists, so before I just took code from the awesome JavaScript for the World Wide Web I went searching for something that was already using nested unordererd lists, and found it in Dave Lindquist's Using Lists for DHTML Menus.

By the time I got the dropdowns plus the tabbed appearance Charlene wants mostly working under Mozilla and Opera (sigh: IE introduces yet another set of visual glitches; CSS sucks!), I'd made a few tweaks to his JavaScript, and I wanted to communicate them back to him.
