|What a nice idea! I like the idea of including the testimonials on the page, nice touch!
And to be nitpicky: The spacing on your stars throughout the page are different. Some have spaces between them and some don't. I realize this is a small thing, but I found it a bit distracting. I know, I'm weird, but I notice those things.
And another nitpicky thing: One one sig, you use the user link to show who made it, and on another, you just show the user name. I think they should be consistent and use the user link.
It's a long page, but it really works. I like how you've shown the sigs and given the image numbers for people to use. The use of color helps break things up. It's a nice layout.
