Free Online HTML Course

While you don't have to know HTML to write a blog, it does come in handy. Did you know that About.com's Guide to Web Design, Jennifer Kyrnin, offers a free HTML course that you can take online?

Technically, the course will teach you XHTML 1.0, which is essentially the same thing as HTML 4.01. Don't know what that means? Sign up for Jennifer's course and learn how understanding HTML can make blogging a bit easier.
