FREE classes on Hewlett-Packard's HP.com site

I was on the HP site looking for some info and noticed they have some FREE online seminars / classes. I just signed up for an XML class. To find the classes, go to the small / medium business computer area of the site click here. On that page you will find a link for the free courses. (I don't know how dependable all the links are, that is why I'm taking you to the one offered)
