Wow, that's really confusing terminology. I would never have guessed that a "check" corresponded to a url or port.
Why do you hide the link to pricing info in the "Features" section? My first question about any product is "How much will it cost me?".
The back button doesn't work in either browser I tried (Chrome and Safari). Click Features, then click Our Customers, then hit back. The page scrolls up about 2 pixels.
