Doug,
The links to pages on your site still don't work in non-IE browsers. The XMLNS junk is still in there.
I have an update to my previous post about the Nvu editor. The latest version does in fact have help/documentation now. Yo may want to try to build your website with that if you can't get Frontpage to generate pure HTML.
By-the-way, I see that you had trouble linking to the page for Tim Lively's video and left a message for him on your home page. The only problem you have there is that you don't have the URL (address) typed in correctly.
You have:
http://www.livelyknives.com/knifemakingvideo.
html
The correct URL is:
http://www.livelyknives.com/knifemakingvideo.
