If you have been using N|vu to create your HTML based website, try to upgrade to KompoZer. KompoZer is actually N|vu, but the developers has fixed some bugs that comes with N|vu. So basically, you will get a “re badged” N|vu on your desktop!
In my opinion, it’s really good. Although there are some dispute on this bug-fixed N|vu and KompoZer issues in the forum, I don’t think it matters most to me. As long as I can edit my HTML files, get my website up into the server, and get my message across to Mount Kinabalu climbers from around the world, it is good enough. After all, it’s a free and open source software.
p.s. N|vu / KompoZer is an open source WYSIWYG HTML generator.
