What is best and free web design software.
I mean WYSIWYG ?
Please don't say Notepad.

Here's two. I used to like the first one more before he improved it, but that's often the case with versions...

I'm a huge fan of Nvu. I tell all my web design clients to use it for maintaining their site and they rarely have problems. They don't need to mess with any code unless they want to, as it is WYSIWYG by default.

...it started off based on the Mozilla Composer code, but now has turned into a quality open source product. Has a long way to go, but it's still very impressive given that all the alternatives easily cost $300+

Consider it a open source version of FrontPage. Only difference is that Nvu is free, makes quality code and is constantly being updated by developers and adding new features.

I just like the normal frontpage, here.

Thanks a lot NVu is winning! I loved Netscape composer and Nvu is what I am looking for.

Cheers

AceHTML , try it. I only used it about 5 times 5 years ago. :(

Glad to help Peter. Definitely check out the Nvu forums. Tons of useful tips and tricks which you may not realize are in Nvu. You'll be amazed :-)
