TSA has a great system called IdeaFactory. It is basically a blog where employees can submit ideas, vote for their favorites, comment and track. OPM recently adopted it from free. If you are interested, send me an e-mail at [email protected]. I can demo it for you and TSA will provide you with a DVD with the code, as well as a manual/SOP on how to manage the program. It's a great program and you can't beat the cost. For samples of similar programs, check out MyStarbucksIdea.com and Dell's Ideastorm.
