No Frontpage Express on IE6 ... so any web-building software to recommend?

[Flaxton]

I'd built a website with a friend (on our separate computers) using Frontpage Express (very basic I know, but that's not a bad thing in my case, and it sufficed quite well) but my new computer has Internet Explorer 6. I've just discovered that they withdrew Frontpage Express by this upgrade, alas, so we'll both need to find some new website building tools to transfer the old pages to and keep on building new ones with. I was just wondering if anyone had any hearty recommendations for similar good (ideally free) website-building software that's safe to download. What have you found to be best, and where might we find it? We'll be grateful for any suggestions if anyone has a free moment to answer.
