Free Innovation Management help with NOVITATE

I recently learned about from a Linkedin group on innovation. What it is, is a web-based service which allows a group of people working on a problem and looking to create innovative solutions to store and share their ideas virtually. This service helps a team keep track of their work and allows them even to invite a broader team to input or comment on their ideas. This is not an open source innovation platform as you would expect from a web based system, this is strictly a closed innovation management tool.
