Crowdsource suggestions and allow people to rate them based on criteria you specify, or to comment. For example, you can solicit policy ideas around a particular topic and let people rate the ideas based on whether they are good, bad, impractical or important. Or you can crowdsource questions for an event, letting people rate them as great, off-topic, important, etc. The page type is a container for suggestions, and includes autoresponse emails and optional auto-tagging.
