Nvu 1.0 preview release is now available.
“Nvu (pronounced N-view, for a “new view”) is a complete Web Authoring System that combines web file management and easy-to-use WYSIWYG (What You See Is What You Get) web page editing.”
Nvu is similar to FrontPage and Dreamweaver, but is open source (free software) and runs on Windows, Mac & Linux. From my brief look I’d say there is some room for improvement (as with every software package) and this has some decent potential as a WYSIWYG editor.
