I couldn't find your demo/feedback site link, and it wasn't until I got back here to complain that I saw that you do actually have one. Went back to the site and still it took 30 seconds of hunting (and another minute to notice the one up top in the little bubble). Nobody off the street will give you that much time. I'd make it as big a priority on the homepage as "sign up".

And speaking of which, the biggest glaring issue with your site is that the "Support" link doesn't go to one of your own feedback sites. Why are you not using your own product? As a potential customer, the immediate answer that springs to mind is "because it's not good enough", and that's the last you'll see of me.
