It's a great package. The person who started the wysiwyg editor Nvu stopped maintaining it after the main sponsor withdrew. Someone else maintained it for a couple of years as Kompozer but I havn't seen an update for a long time. Recently, the original programmer for Nvu starter a successor wysiwyg HTML editor called BlueGriffon. It is open source and available for Windows, Mac and even Linux.
You can get BlueGriffon here.
