You guys will have to bend like reeds in the wind, I'm afraid. You can't have new functionality and not the navigation to go with it. The site is growing. Just the way things are.

Besides, what exactly is "going on" in the mockup that isn't "going on" in the current software? The left nav? That's all I can see. If anything, the interface is cleaner because the icons and links have been replaced by tidy dropdown menus.

That mockup is also way out of date, btw.

Change is healthy guys. It stirs something that sleeps deep inside. The sleeper must awaken.
