RoundCube: Another hot AJAXy webmail package

RoundCube is a very impressive open source webmail client written in PHP with a MySQL back-end. While not nearly as featureful as last week's Zimbra, it feels much more lightweight and (in my opinion) is somewhat more attractive. It supports drag-and-drop and autocompletes e-mail addresses, and the XHTML interface is completely skinnable with CSS. There's a live demo on the site, but beware, RoundCube is still alpha software.
