I visited your site and have a few quick comments:

1. I'm not a fan of pop-up windows. You may want to somehow incorporate that information in your site.

2. There is a lot of navigation links in your sidebar. I suggest to either remove a few, or organize them into specific topics.

3. I would increase the size of your font in the content section - maybe make it at least the same size as your links on the left.
