Integrate IdeaStorm into Dell.com
Simple but novel idea, consider tightly integrating IdeaStorm and Dell.com. Conceptually this would offer the ability to add and idea on a given product while looking at the product on Dell.com
While viewing your product (Laptop, accessories, servers, etc.) add a link or button that says "submit an idea on this product" at the bottom of this page.
Ideally your Dell.com ID would be tied to your IdeaStorm ID so that you do not have to login a second time.
