SEOmoz.com is a search engine optimization company in Seattle. They`re running an SEO quiz so people can test their SEO skills. Fun stuff! It`s here: http://www.seomoz.org/seo-expert-quiz
Some of the questions are really arcane. I know most of the SEO basics but I learned a number of interesting things on the quiz. I clocked in as an "SEO Newbie" (one step above "novice") which is about what I figured.
There are also a number of excellent articles and FAQs there as well, useful for "newbies" like myself.
