Well, until I remember, I’ll just tell you that I’ve been digging on AboutUs.org lately. They’ve got some really easy to use tools for testing your site, but the heart of it is a giant wiki for any website on the internet.

Links are nofollow by default, but if you do a good job with your page, they’ll mark dofollow after a request to a live human.
Oh, they also have a blog with some seo tips, and a frequent weekly project page to improve (generally a charity picked by volunteers to work on as a group).
