How can I turn a .txt file into an .html file?

[the diva]

I don't remember how I did it before Front Page! Now I want to start a blog, I've registered my domain and its live as an add-on domain to one that I write with Front Page. I wrote a short "I'll be here soon" file in html, but can't manage to get it from Wordpad or Word to an .htm file. It keeps calling itself "web page file" and when I upload it, I can open it (cached in my computer) but no one else gets it at all. I know it's because it's not a real htm. file. Yoiks What am I missing here?
