CMEs: How do the puzzle pieces fit together?

This review consists of questions to participants in the S-RAMP Symposium (S3) on CMEs and Coronal Holes, as well as to a few others, and their responses in a "town meeting" format (originally conducted on Hugh Hudson's website). Here we deal only with CMEs. The questions we ask aim at probing the weaknesses of existing models and highlighting controversies, thereby providing guidance toward a more complete view of solar eruptions. Topics covered include: the "solar flare myth", flux ropes, new phenomena (EIT waves, dimmings, global brightenings), helicity and sigmoids, and transequatorial loops (as sources of CMEs). Although this is a review, we're more concerned here with what is not known than what is already agreed upon. We asked people to speculate freely in advance of the observational, analytical, and theoretical work that will provide definitive answers-this is not the standard Scientific Method at work!
