http://www.teampages.comFirst of all, congrats on getting TeamPages up and running. If the numbers on the home page are accurate, it seems you're already getting nice traction.
My first thought when I saw the site was that the design is pretty solid (very clean, easy to navigate) especially for the demographic you're targeting. For me, personally, the design feels a bit corporate and that's reinforced with the 800-number being front and center. I love great customer service, but I prefer dealing with small companies and this feels larger than I think it actually is - I guess it really depends on the image you're trying to project.
Apart from that, I immediately got a good sense of what your site is about from the copy - but I'd rather see first, then read. The only images of the product on the homepage are too small to really appreciate, and the example sites are buried at the bottom of the page. I'd consider bringing the product front and center (example: Basecamp homepage).
I didn't register and test the product, but the pricing seems very fair. However, I don't think you should be putting ads up on a paid package (Pro). I think you can differentiate the [Pro] and [Pro + Ad-Free] accounts so that you have three levels of pricing, with neither of the paid options having advertisements. If I had any critique with regards to the pricing page design, it would be that the options are a bit overwhelming, especially in the Basic Features section, where every option is included with each plan - it seems to me that you could restrict some of these options on certain plans to create the differentiation I mentioned before.
One last thing that stuck out to me was that the site URLs are pretty long, and it would be tough to remember my team site if it was told to me in person by a parent or player - you might consider letting them choose vanity URLs (ex: teampages.com/washington-capitals-hockey).
Overally though, great job, and congrats again on getting things up and running. Good luck!
