How can I collect credits?

Easy one: submit good ideas, give good comments and rate as many ideas as fair and diverse as possible.

So in general there are three credit categories:

• Idea credits: the better your idea ranks, the more credits you get. And obviously a sold or featured idea makes some extra credit points…
• Comment credits: Give feedback and get good credit points for it. People give you the thumbs up for your comments? That makes for extra points.
• Rating credits: rate as many ideas as fair and diverse as possible and you get your rating credits going.
