Easy to use website builder

I signed up for Yahoo! Small Business services in April to develop my website, www.writingandmarketing.com. I've been having a little trouble uploading PDFs to the site... until today. They upgraded the website editing software I use (there are actually 4 to choose from, of course I picked the one that's easiest) and it's really pretty cool. It's called SiteBuilder, and it's good for people who don't want to learn HTML and have flashing crap running across the screen. You can build a store with it too... which I may do eventually.
