An Idea can be a thought, something new you just created, or a shout out about a new development. You can choose to post an Idea to one or more Spaces and start collaborating with other innovators. By posting a new idea, you are also claiming a stake as the first to come up with the idea (think IP protection).
Still working on your idea? Save the idea to fine-tune it anytime you want before publishing it to a Space.
