We're looking for feedback on Celtx - collaboration software for film, tv and new media projects. It has basic script writing/editing and production breakdown features. If you're interested please visit http://www.celtx.com.

For tech folks - Celtx is an open source application (MPL) developed using the Mozilla Application Framework. It runs "inside" of Firefox, an open source browser for Mac, Windows and Linux. More tech info is available at http://celtx.mozdev.org .
