A few thoughts.
1. Remove this banner. I do not think it needed as you have the text link at the top. And it makes the site look ugly.
2. Put the logo in the center of the site, and the text under it (where you sign in and so on).
3. Get rid of the google advert. It makes the site look ugly and I bet it will not generate much, plus will put some people off adding products to your site.
4. Do your own youtube film. It will help get you more hits to your site.
5. More info on how your site works. I looked and had no idea if I send you my stuff or anything.
