This looks very neat. I haven't used SQL much and while I'm somewhat familiar with it I'll run through it to brush up a bit, thanks! Also, it took me a minute

This looks very neat. I haven't used SQL much and while I'm somewhat familiar with it I'll run through it to brush up a bit, thanks! Also, it took me a minute to find the table of contents - I was looking for an "Index" link or something at the bottom of the page near the previous/next lesson links. For reference, you have to hover over the "Interactive Tutorial" tab at the top of the page.
