I guess the first thing I can think of was finding it. Now that I did, under the "basics" section here is a direct link: http://www.flyanglersonline.com/begin/knots/
Nice section.
I do enjoy the knot wars site and the videos of testing many knots in a head to head competition. The other articles are ones that I have saved to my favorites and have a nice take on knot selection.
