I’ve been playing around with the NVU web page editor, an open source application available for Windows, Mac and Linux. So far it’s good stuff, certainly rivalling Frontpage, and heaps better for new users looking for something cheap or free other than MS Word (which has well-known problems).
Now up to version 1.0, it probably isn’t on a par with Dreamweaver, but for basic WYSIWYG web page editing, definitely worth a look.
